Question

The length and breadth are in ratio 4:3 .If perimeter is 140.find it's area

Answer 1

Step-by-step explanation:

Let the length and breadth of the rectangle be 5x,2x.

Then perimeter will be 2(5x+2x)=14x.

According to the problem,

14x=140

or, x=10.

Then length and breadth will be 50 cm and 20 cm.

Then area will be 50×20=1000 cm
