It depends on the shape.
Let's say your lawn is 1 foot by 100 feet, which equals 100 square feet, then the surrounding measurement, called the 'perimeter', is 1+ 1+ 100+ 100 = 202 feet.
Or, if the lawn is, say, 4 feet by 25 feet, which equals 100 square feet, the perimeter is 4+ 4+ 25+ 25 = 58 feet.
If the lawn is perfectly square, its size would be 10 feet by 10 feet, and the perimeter is 10+ 10+ 10+ 10+ = 40 feet.
The same is true for all dimensions in between: the perimeter changes as the shape of the lawn changes.
10 feet by 10 feet
700 square yards, because it says he mows the lawn in 2 days, and he mows 350 square yards in 1 day, so multiply by 2 and you get 700. I think. So are you cheating on your homework or something?
I'm going to guess that the figures in your question are percents. After lunch he cuts 34% of the 23% he has left (If I'm reading the question correctly). "Of" usually means to multiply. In this case .34 times .23 equals .0782, or a little under 8%. He cut a little under 8% of the lawn after lunch.
To get five dollars fast, you can wash cars, or help people carry their groceries or mow their lawn.
Usually, the higher the number, the higher the grass will be cut. The higher of which number? If you have a riding mower, the numbers will be on the slot where the the lever for the blades is located. If you have a regular push mower, there will be no numbers. In that case, the higher slot that you use will mean a shorter cut of the grass. Okay, what and where is the slot located?
Unfortunately, "It Depends" - - To determine square footage, you have to know whether the lawn is square, rectangular, circular, or some other shape. Assuming a rectangle (or square), the square footage is determined by multiplying the length by the width. Linear footage is determined by adding 2 times the length plus 2 times the width. If the lawn is a square, there is only one answer (as there is only one solution which will give 1500 square feet: length and width of 38.73-some odd decimal, meaning 2 times length and 2 times width gives a linear footage of some 154.92 feet). However, if the lawn is rectangular, there are an infinite number of answers. Giving three examples to show the range: 1) If the lawn is 50 feet long by 30 feet wide, that will give (50x30), or 1500 square feet of area and ([50x2]+[30x2]), or 160 linear feet. 2) If the lawn is 100 feet long by 15 feet wide, that will give (100x15), or 1500 square feet of area and ([100x2]+[15x2]), or 230 linear feet. 3) If the lawn is an alleyway in the middle of a big city and 1500 feet long by 1 foot wide, that will still give the required (1500x1), or 1500 square feet of area...but a whopping ([1500x2]+[1x2]), or 3002 linear feet around! (Note that the square gives the least linear footage possible for a rectangular-shaped lawn) Have fun figuring out circular, elliptoid, and other funny shaped lawns...

IF the lawn is rectangular, then the area is (395 x 236) = 93,220 square feet, or about 0.47 acre.
If the lawn is rectangular (or square) then measure its length and width - in feet. The area is length * width. If it is odd shaped, try and mark out rectangles, measure their area as above and then add together the answers for each rectangle.
If the lawn is twice as long as it is wide, and length times width is 288, then 3x = 288, or x = 96. The lawn is then 96 by 192 feet. This means that the perimeter is 576 feet (96 + 96 + 192 + 192).
If the length of the enclosure is 21 feet then the width is 12 feet. 21*12 = 252 sq ft
The lawn is 18-ft long and 8-ft wide. Write down all the factors of 144, and find two of them that add up to 26. (P.S.: Sooner or later, you'll have to learn to do this on your own. You can't go through life asking somebody else to do it for you every time you need it.)
17 feet.
28 feet long and wide
10 feet by 10 feet
150 ft * 160 ft = 24 000 square feet. 4 000 sq feet of lawn requires one pound of seeds so 24 000 sq ft of lawn will require 6 pounds of seed.
the answer is 160x144
