Question

A carpet is placed in the middle of a room 15m long and 12m broad so that it leaves a uniform width of 1m around it . find the area and the cost of the carpet at Rupee 500 square meter

Answer 1

`130m^(2)` ,
`65.000 rs`

Explanation:

Given Length = 15m
Given Breadth = 12m

Since there is a 1m gap between the sides,

Actual Length = 15 - 2 = 13m
Actual Breadth = 12 - 2 = 10m

From here find the Area:

L * B = AR of a cuboid , so

13 x 10 =
`130m^(2)` is the Area

for every
`m^(2)` it is 500 rupees, so for
`130m^(2)` ,

130 * 500 = 65,000 rupees.
