Math Tutor or Teacher: amanpreet.jaggi

Hi,

Let width = w

Length = l

now according to the question

l = 3w+7

Perimeter = 2(w+l) = 462 .... equation 1

Substituting values of l and w in equation 1 we get

462 = 2(w+3w+7)

231 = 4w+7

224 = 4w

w = 56 yards

Now

l = 3w+7

l = 3*56+7

l=175 yards

So width = 56 yards and length = 175 yards
