The area of a rectangle is 460 square meters. If the length is 15% more than the breadth, what is the breadth of the rectangular field?

A 15 meters

B 26 meters

C 34.5 meters

D 20 meters

Solution

Correct Answer: Option D

Let breadth =x metres. Then length =(115x/100)metres.

x∗115x/100=460

x2=(460*100/115)

x2=400

x=20
