Answer 1

`\bf Correct Question`

the length of a square room is 8m . what will be the cost of carpeting the room with carpet of width 128cm at the rate of Rs 120 per meter square?

`\\ \\`

Given :

• L = 8m
• Per meter ² cost = 120
• W = 128 cm = 1.28 m

`\\ \\`

To find :-

• Total cost of carpeting

`\\ \\`

So to find cost we have to find Area

`\\ \\`

We know

`\dashrightarrow \sf Area = l * b`

`\\`

`\dashrightarrow \sf Area = 8 * 1.28 {m}^(2)`

`\\`

`\dashrightarrow \sf Area =10.24{m}^(2)`

`\\`

Total Cost :-

• Area × Cost of 1 meter ²
• = 10.24 × 120
• = ₹ 1,228.8

`\therefore \underline {\textsf{\textbf{Total cost of carpeting is equal to \red{1228.8 rupees}}}}`
