Question

The area of a rectangleisb108 cm ² , it's breadth is 9 cm , find its perimeter​

Answer 1

Answer:

42 cm is the answer

Step-by-step explanation:

we know that,

area = length × breadth

108 cm^2 = length × 9 cm

length = 12 cm

then,

perimeter = 2 (l+b)

= 2 (12 + 9)

= 2 × 21

perimeter = 42 cm
