Question

question 6 points 2 a wall in the form of a rectangle has a length of 15 m and a width of 10 m. find the area of the wall. if the cost of painting the wall is $5 per square meter, find the cost for painting the entire wall.

Explanation:

Step1: Calculate the area of the rectangular wall

The formula for the area of a rectangle is \( A = \text{length} \times \text{width} \). Given length \( l = 15 \, \text{m} \) and width \( w = 10 \, \text{m} \), we substitute these values into the formula:
\( A = 15 \times 10 = 150 \, \text{square meters} \)

Step2: Calculate the cost of painting the wall

The cost per square meter is $5, and the area is 150 square meters. To find the total cost, we multiply the area by the cost per square meter:
\( \text{Total Cost} = 150 \times 5 = 750 \, \text{dollars} \)

Answer:

The area of the wall is \( 150 \, \text{m}^2 \) and the cost for painting the entire wall is $750.
