Question

A rhombus shaped sheet with perimeter 40 cm and one diagonal 12 cm, is painted on both sides at the rate of Rs 5 per m 2 . Find the cost of painting.

Answer 1

Answer:

a=1/2*d1*d2

40=1/2*12*d2

40/6=d2

6.66cm

paint on 1st side=6.66*5

                           =33.3

paint on both side =33.3+33.3

66.6
