Question

The length of a rectangular piece of land is 35ft more than four times its width. The perimeter is 770ft. Find its dimensions.

Answer 1

well let the width be w

then the length is l = w + 35

and the perimeter is

770 = 2 l + 2 w

substitute the value for l

770 = 2(w + 35) + 2w

simplify and solve for w

when you have w use l = w+ 35 to find the length

Answer 2

Thanks a lot :)
