Answer 2

Concept:

The basic concept of mathematics operations i.e. division. The division is the seperation of two numbers in parts.

Given:

The total cost of painting the sunshade = Rs. 900

The rate of painting the sunshade = Rs. 2 per sq. m

Find:

We are asked to find the area of sun shade which is in the form of an isosceles trapezium.​

Solution:

We have,

The total cost of painting the sunshade = Rs. 900

The rate of painting the sunshade = Rs. 2 per sq. m

So,

Now,  

To find the area of sun shade divide the total cost of painting by the rate of painting per square meter,

i.e.

The area of sun shade = 900 / 2 = 450 square meter

Hence, the area of a sun shade which is in the form of an isosceles trapezium is 450 square meters.​
