Question

A room is 8 m long and 5m wide. Find the cost of the flooring tiles at the rate of rs. 40m that used in verandah of 1.5m width which surrounded the room

Answer 1

Answer:

The cost of flooring tiles in verandah is ₹1920.

Step-by-step explanation:

Given:

Length of the room = 8 m

Breadth of the room = 5 m

Width of Verandah = 1.5 m

Cost of flooring tiles for 1 m = ₹40

To Find:

Cost of tiling verandah

Solution:

Let the room including be named as Rectangle ABCD.

Let the room excluding be named as Rectangle PQRS.

Length of ABCD = 8 m + (1.5 m + 1.5 m) = 11 m

Breadth of ABCD = 5 m + (1.5 m + 1.5 m) = 8 m

Area of ABCD = 11 m × 8 m = 88 m²

Area of PQRS = 8 m × 5 m

$\bold{\boxed{Area \ of \ PQRS = 40 m^2}}$

Area of Verandah = 88 m² - 40 m²

⇒ 48 m²

$\bold{\boxed{Area \ of \ Verandah = 48 m^2}}$

Cost of flooring tiles of Verandah = ₹40 × 48 m²

⇒ ₹1,920

$\bold{\boxed{Cost \ of \ flooring \ tiles \ of \ Verandah = Rs. \ 1,920}}$
