Question

5. The breadth of a rectangle is 12 m. If its length is 3
times its breadth, find the perimeter of the rectangle.​

Answer 1

72 m

Step-by-step explanation:

Breadth = 12 m

length = 2 × breadth

= 2 × 12 m

= 24 m

Perimeter = 2(length + breadth)

= 2(24m + 12m)

= 2 × 36 m

= 72 m

Answer 2

Answer:

Step-by-step explanation:

Given: B = 12 , L = 3*12 = 36

Perimeter = 2(l+b)          

                    2(12+36)

                    2 x 48

                    96
