Let the length be L, then the width = L-3
The area = L x W = L x (L-3) = L2-3L
the area is 340 which = L2 - 3L, 340 = L2-3L, 340-340=L2-3L-340
So, L2-3L-340 =0 Factoring this, (L-20)(L+17) = 0
Set L-20 equal to zero, L-20 = 0, L-20+20=+20, L=20
so, L=20 inches and width = L-3=20-3=17 inches
L=-17 is not a solution since length can't be negative.
Your answer is
length = 20 inches, width = 17 inches
They are: 3 inches and 5 inches respectively
A rectangle with one side that is double the length of the other side can be seen as two squares beside each other, that are half the area of the original rectangle, in this case 18 square inches / 2 = 9 square inches. The side of a square is the square root of the area, in this case the square root of 9 square inches, which is 3 inches. Now think about the rectangle again. What we just counted was the side of a square that made up one half of the rectangle you wanted to calculate the area of. So the shorter side of the rectangle is the same as our square, and the longer side is double the length. So the width of the rectangle is 3 inches, and the length is 2 * 3 inches = 6 inches. Or: Area = length x width (A=lw) Area = 18 (in2) Width = w Length = twice width (2w) 18 = (2w)w 18 = 2w2 9 = w2 3 = w The width is 3 in., the length (2w) is 6 in.
The dimensions are: length = 15 inches and width = 7 inches Check: 15*7 = 105 square inches
Area=Length*Width A=14 Inches*2 Inches A= 28 square inches or 28 in2
Let the width be (x-3) and the length be x: width*length = area (x-3)*x = 340 square inches x2-3x-340 = 0 Solving the above quadratic equation works out as: x = -17 or x = 20 it must be the latter because dimensions can't be negative. Therefore: length = 20 inches and width = 17 inches Check: 20*17 = 340 square inches
The area of a rectangle is 56.25 square inches. The length of the rectangle is12.5 inches what is the width
A square is a rectangle, rectangles don't have to be squares but squares have to be rectangles.
if a rectangle is 450 square inches and the length is 24 inches what is the width?
12
What is the length of the rectangle? If you had said one of the sides of a square was 3 inches, you could multiply 3 inches by 3 inches to get the value in square inches.Area = 3l square inches, where l = length of the rectangle in inches.
10 inches
28 inches
Its length is 1+ square root of 66 ft and its width is -1+ square root of 66 ft
9 inches
2x4
Technically, yes, because technically, a square is just a special kind of rectangle. So, technically, any rectangle with its length and width the same size is congruent to any other rectangle whose length and width are that size, and they're also both squares.
The area of rectangle is : 78.0
