Question

A man has to build a rhombus shaped swimming pool. One of the diagonal is 13 m and the other is twice the first one. Then find the area of the swimming pool and also find the cost of cementing the floor at the rate of ` 15 per sq.Cm

Answer 1

Answer:

Area of the pool is 169 m² and cost of cementing is Rs. 2532.

Step-by-step explanation:

Given:

Swimming pool is in shape of Rhombus.

Length of the one diagonal = 13 m

Length of 2nd Diagonal = 2(13) = 26 m

To find: Area of the Swimming pool and cost of cementing the pool at rate of 15 per cm²

We know that Area of the Rhombus = 1/2 × product of the diagonal.

Area of the Swimming pool = 1/2 × 13 × 26

                                              = 13 × 13

                                              = 169 m²

Cost of Cementing the floor = 169 × 15 = Rs. 2535

Therefore, Area of the pool is 169 m² and cost of cementing is Rs. 2532.
