Question

samira is painting a wall that is 10 feet high and 60 feet wide. one gallon of paint will cover 400 square feet of wall space. area of rectangle = lw l = length w = width

Explanation:

Step1: Calculate the area of the wall

The wall is a rectangle with length \( l = 60 \) feet and width \( w = 10 \) feet. Using the formula for the area of a rectangle \( A = lw \), we substitute the values:
\( A = 60 \times 10 = 600 \) square feet.

Step2: Determine the amount of paint needed

One gallon of paint covers 400 square feet. To find the number of gallons needed, we divide the area of the wall by the coverage per gallon:
\( \text{Gallons needed} = \frac{600}{400} = 1.5 \)

Answer:

Samira needs 1.5 gallons of paint.
