Question

The perimeter of a rectangular pool is 100 m and its length is 30 m. Find its breadth.

Answer 1

Given that perimeter of a rectangular pool = 100 m and length = 30 m
Since, perimeter of a rectangle = 2 (length + breadth)
⇒ 2 (30 m + breadth) = 100 m
⇒ (30 m + breadth)$=\frac{100}{2}\mathrm{m}=50\mathrm{m}$
⇒ breadth = 50 m – 30 m
⇒ breadth = 20 m
Thus, the breadth of the rectangular pool = 20 m
