Question

a rhombus sheet whose perimeter is 32 and whose one diagonal is 10 metre long is painted on both side at the rate of 5 per metre square find the cost of paintinh

Answer 1

We know that perimeter=32

p=4×side

32 =4 ×s

s=8

the area of rhombus is half the product of its diagonal

area =1/2 ×10×10

=50m^2

The area of both the sides =50×2 =100m^2

The cost of painting will be 100×5=500
