Question : 22

Total: 40

Solution:

Concept:

The area of a rectangle is the total space enclosed within its sides, calculated as the product of its length and breadth.

Explanation:

Here, the floor is a rectangle.

Its length is

20\,\text{m}

and its breadth is

15\,\text{m}

Use the formula:

\text{Area} = \text{Length} \times \text{Breadth}

Substitute the given values:

\text{Area} = 20\,\text{m} \times 15\,\text{m}

Multiply the numbers and the units:

20 \times 15 = 300

and

\text{m} \times \text{m} = \text{m}^2

Therefore,

\text{Area} = 300\,\text{m}^2

This value corresponds to option D.

Answer:

300\,\text{m}^2
