Question

A rectangle has side lengths of (7.5a - 1.5b) cm, (3,5a + 4.5c) cm, and (6.5C + 2a) cm, and (8.50 -6.5c). Which expression represents the perimeter, in centimeters, of the

rectangle?

Answer 1

Explanation:

our lengths are:

7.5a-1.5b, 3.5a+4.5b, 6.5c+2a, 8.5-6.5c

P=7.5a+3.5a+2a-1.5b+4.5b+6.5c-6.5c+8.5=16a+3b+8.5
