Question

the perimeter of a rectangle is 5x and its length 3/2 x. if the area of the rectangle is 294, what is the value of x?

Answer 1

x=14

Explanation:

A = (l)(w) 294 = ((3/2)x)(w)w = 196/xP = 2l + 2w5x = 2((3/2)x) + 2w

5x = 2((3/2)x) + 2(196/x)

x = 14, -14

-since negative values can't be used for side lengths,

x is just 14.
