Hope this helps

Answer 2

✬ Area = 2600 m² ✬

Step-by-step explanation:

Given:

• A floor of hall is completely covered by 26 carpets.
• Dimensions of carpet is 4 m by 25 m.

To Find:

• What is the area of floor of hall.

Solution: Since floor of hall can be completely covered with 26 carpets. Therefore,

➯ Area of floor = Area of 26 carpets.

Now,

• Length of carpet = 4 m.
• Breadth of carpet = 25 m.

Carpet is in rectangular form so,

★ Area of Carpet = (Length)•(Breadth) ★

$\implies{\rm }$ Area of 1 carpet = (4)(25)

$\implies{\rm }$ 100 m²

∴ Area of 26 carpets = Area of 1 carpet $\times$ 26

➯ 100 $\times$ 26

➯ 2600 m²

Hence, Area of floor will be also of 2600 m².
