Question

The perimeter of a rectangle is 500 cm and its length is 150 cm , then its breadth is

Answer 1

Answer:

100 m

Step-by-step explanation:

Perimeter of a rectangle = 2 x (length + breadth)

⇒ 500 m = 2x(150 m + breadth)

⇒ 250 m – 150 m = breadth

∴ breadth = 100 m

Answer 2

Answer:

Perimeter of a rectangle = 2 x (length + breadth) ⇒ 500 m = 2x(150 m + breadth) ⇒ 250 m – 150 m = breadth ∴ breadth = 100 m

(ii) Area of rectangular field = length x breadth = 150 m x 100 m = 15000 m²

(iii) Cost of ploughing the field at the rate of = Rs 1.20 per square m² = area of the field x rate of ploughing = 15000 m² x Rs 1.20 per square metre = Rs 15000 x 1.20 = Rs 18000Read more on Sarthaks.com - https://www.sarthaks.com/173771/the-perimeter-of-a-rectangular-field-is-500-m-and-its-length-150-m-find-i-its-breadth
