Question

the perimeter of a rectangular concrete slab is 114 feet and its area is 702 square feet. Find the dimensions of the rectangle

Answer 1

you have to substitude for l or w and solve the equation

Answer 2

I am sorry can you break it down for me.

Answer 3

lets solve for w = 702 / l

the new equation is

2* (l + 702 / l ) = 114

Answer 4

divide by 2

L + 702/ L = 57

Answer 5

get common denominators and

(L^2 + 702) / L = 57

Answer 6

multiply by L both side

L^2 +702 = 57 L
