Question

What is the perimeter of a rectangle whose sides are of lengths (3z+2) units and (2z+3) units

Answer 1

2(3z+2)+2(2z+3)
6z+4+4z+6
6z+4z+4+6
(10z+10) units

Hope this helps :)

Answer 2

We know, the Perimeter = 2(l + w)
Here., l = 3z + 2
w = 2z + 3

Substitute their values,
P = 2(3z + 2 + 2z + 3)
P = 2(5z + 5)
P = 10z + 10

In short, Your Answer would be 10z + 10

Hope this helps!
