Question

A rohmbus sheet whose perimeters 32mand whose one diagonalis 10 m long it painted on both sides at the rate ofrupee 5 per m sq find the coast of painting

Answer 1

Answer:

Perimeter = 32 m,

So, length of a side =32/4=8m,

and Diagonal of a rhombus = 10m,

As, we know that,

The halves of diagonals and a side of a rhombus from a right angled triangle with side as hypotenuse.

Let the length of the other diagonal =2x.

The measure of the another diagonal of the rhombus = 2*\sqrt { 39 } =2\sqrt { 39 } m

So, Area of the rhombus =1/2*Diagonal of a rhombus*Measure of the another diagonal

painted on both sides at the rate of Rs 5 per m2

Cost = area of both side*5=2*62.45*5=624.50 Rs

Answer (B) Rs. 625
