The figure shows two identical shade squares, each of side 9 cm, placed within a rectangle. What is the perimeter of the rectangle?

Answer 2

Answer:

Sides od square is 9 cm

it's equal from all sides .

So ,

9 + 9 + 9 = 27

L = 27

9 + 9 = 18

B = 18 ,

perimeter of rectangle = 2(l+b)

= 2(27+18)

= 2 × 45

= 90

the perimeter of rectangle is 90 cm
