Question

the length of a rectangle is 20 m and breadth is 15 M how much distance will be covered in going around it once​

Answer 1

Length = 20 m

Breadth = 15 m

Distance covered in one round = Perimeter of rectangle

Perimeter = 2 (lenght + breadth)

= 2 (20 + 15)

= 2 (35)

= 70m

Hope it helps.

Answer 2

length = 20m

breadth = 15m

perimeter = 2 (l+b)

= 2(20+15)m

= 2 × 35 m

= 70 m

the distance covered in going around it once is 70m.

hope you understand.
