Question

if a yard has an area of 96 sq ft ..  the width of the yard is 4 ft less than the length what is the perimeter in ft of the yard how can i solve this ?my head is in knots

ivettef365 · Answer

4 ft less than the length
so it is L - 4

ivettef365 · Answer

Formula is P = 2L + 2W
W = (L-4)

so 96 = 2L + 2(L-4)   solve for L

anonymous · Answer

i understand that but how can i use 4 an d96 to solve

anonymous · Answer

Like she said before you make an equation equal to 96 using the variable L nd -4.

anonymous · Answer

You agree with there being two sides equalling to L and two sides equaling to L-4 right?

anonymous · Answer

yes

anonymous · Answer

So make an equation out of that....

anonymous · Answer

2L+2(L-4)=96

anonymous · Answer

ok il try solving thx

anonymous · Answer

But remember your not finished after that! you have to add up all the sides to get the perimeter.
