Question

Each side of a square classroom is 7 meters long. The school wants to replace the carpet in the classroom with new carpet that costs $50. 00 per square meter. How much will the new carpet cost?

Answer 1

$2450

Explanation:

You want the cost of carpeting a 7 m square classroom with carpet costing $50 per square meter.

Area

The area of the classroom is the product of its dimensions:

A = s²

A = (7 m)² = 49 m²

Cost

The cost of the carpet is the product of the number of square meters and the cost of carpet for each.

Cost = (49 m²)($50/m²) = $(49·50) = $2450

The new carpet will cost $2450.
