Question

If the perimeter of protractor is 72cm, calculate its area.(pi=22/7)
plz solve dis important sum.... ​

Answer 1

hope that you can understand now

Answer 2

Perimeter = 72 cm

πr + 2r = 72

r(π + 2) =72

r = 72/π +2

r = 72*7/36

r = 14

Area = πr^2/2

Area = 22/7*14*14/2

Area = 22*14

Area = 308 cm^2
