Question

18. The length of a rectangle is three times its breadth. If the area of the rectangle is
1875 sq. cm, find its perimeter.
​

Answer 1

Answer:

I am coming directly to the point, please try to understand.

length=3x

breadth=x

perimeter=2(l+b)=1875

$= > 2(3x + x) = 1875 \\ = > 4x = 1875 \div 2 = 937.5 \\ = > x = 937.5 \div 4 \\ = > x = 234.37$
