Question

The area of a rectangular field is 1600 sq m. If the length of the field is 80 m, find the perimeter of the field.

Answer 1

Area of the rectangular field = 1600 m²

⇒ length × breadth= 1600 m²

⇒ 80 m × breadth = 1600 m²

⇒ breadth = 1600 m²/ 80 m = 20 m

Now, perimeter of the rectangular field = 2(length + breadth)

= 2(80 + 20) m

= 2 × 100 m = 200 m
