The area of a rectangle is 60 square meters. If the length is increased by 25 % and the width is increased by 10 % , what is the new area?

Question

Enter the exact answer.

Answer 1

Let L = Length

W = Width

Then at first, LW = 60

After the expansion

(1.25L)(1.1W) = ? = (1.25L)(1.1)(60/L) = 82.5

So, the new area is 82.5 m²
