Question

What is the maximum area of rectangle whose perimeter is 18 cm?

Answer 1

Answer:

We Know that, Perimeter = 2 * ( L + B )

( L + B ) = 9

Let us assume that the possible cases of L * B are :

5 * 4 = 20

6 * 3 = 18

7 * 2 = 14

8 * 1 = 8

Hence, the maximum area is 20cm²

Answer 2

Answer:

Hence, the maximum area is 20 cm² .
