a rectangular garden has a width of 90 ft the perimeter of the gaarden is 500 ft.what is the length

Answer 1

Draw a picture of a rectangle, showing 2 short sides (widths) and 2 long sides (lengths). Each of the short sides is 90. How much do the two short sides add up to? Subtract that sum (180) from the total of all 4 sides (500). 500 - 180 = 320. The 2 equal lengths must add up to 320; therefore each of them is half of 320, or 160.

Answer 2

A rectangle has two equal long sides and two equal short sides, length (L) and width (W). Perimeter = 2L + 2W.

We are given P = 500 and W = 90. Can you substitute into the equation and solve for L? Try drawing a picture to see if you can figure out the length that way as well.

Answer 3

p = 2l + 2w = 2(l + w)

500 = 2(l + 90)

500/2 = l + 90

250 = l + 90

l = 160 ft
