Question

The perimeter of a rectangular picture frame can be represented by the expression 6x,where x is one of the side lengths. Rewrite the expression as the sum of the four side lengths.

Answer 1

Perimeter is formed by 4 side lengths.

Divide perimeter in 4 parts

x= side length

P = 6x = x + x + 4x

then length of the other sides lengths is= 2x

So then ANSWER IS

P= x + x + 2x + 2x
