Question

If the length,l, of the yard is 18 feet longer than the width ,w, of the yard, what is the area of the yard , in square yard

Answer 1

Answer:  The area is $w^{2}$ + 18w

Step-by-step explanation:

We could represent the length of the yard by  l = w+18    and the width as w .

And to find the area we will have to multiply  the length by the width.

A=  w(w+18 )    multiply

A= $w^{2}$ + 18w

Answer 2

Answer:

27^2 yards

Step-by-step explanation:

Perimeter  = 2W + 2L  ..... and the  width is 18 more than the length....therefore  

Perimeter  = 2[L + 18] + 2L

72  = 2L + 36 + 2L

72  = 4L  + 36      subtract 36 from each side

36  =  4L    divide both sides by 4

9  = L      and the width is 18 more   = 27

So....the area  = W x L    =  27 x 9   =  243 ft^2 = 27^2 yards

(divide the area value by 9 )
