You cannot find the width or length if all you know is the area. But your question gave the answer: The width is 18.
To find the area of a rectangle, you multiply the length by the width. First, convert the width and length to millimeters by multiplying by 10 (since 1 cm = 10 mm). So, the width becomes 87 mm and the length becomes 93 mm. Then, multiply the width by the length: 87 mm * 93 mm = 8091 square millimeters. Therefore, the area of the rectangle is 8091 square millimeters.
14355 yds2 Let l represent the length and w the width. Perimeter equals 2*l+2*w. From the information in the problem, we have two equations and two unknowns: 2l+2w=504 l=2w-9 Substitute l from the second equation into the first equation and solve for w: 2(2w-9)+2w=504 4w-18+2w=504 6w-18=504 6w=522 w=522/6=87 Now, substitue w=87 into the second equation above to find l: l=2*87-9=165 With the length and width determined, we can find the area: Area = l*w=165*87=14355 yds2
To find the area of a square lot, we do the same thing as we would for a rectangular lot. With a rectantular lot, it's length times width. With a square lot (a square being a special case of a rectangle where the length equals the width), we just multiply one side by another side. Another way to say that is that we square a side to find the area of a square. In this case, 87 feet x 87 feet = 87 feet2 = 7569 square feet (or ft2).
Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.
Area = Length*Width so Width = Area/Length = 40/[10+sqrt(13)] = 40*[10-sqrt(13)] / [10+sqrt(13)][10-sqrt(13)]= [400 - 40*sqrt(13)] / [100 - 13]= 400/87 - 40*sqrt(13)/87= 40/87*[10 - sqrt(13)]= 2.94 approx.
It means it measures 87 units across.
87/18 = 29/6 when simplified
90 cm
87/54 = 29/18
Let the length be 2x+3 and the width be x: So: 2*(2x+3+x) = 258 => x = 42 feet Therefore: length = 87 feet and width = 42 feet Check: 2*(87+42) = 256 feet
87/54 = 29/18
