Question

1. a group of students is painting the flag of brunei for a geography project. joseph is responsible for painting only the background colors of the flag. how many square inches will he cover with white paint? (hint: use the formula a = bh.) (example 1)

Explanation:

Step1: Identify the base and height of the white - colored part

The white part of the flag forms a rectangle. The base $b$ of the white - colored rectangle is $72$ inches and the height $h$ is $3.5$ inches. We get the height by calculating $\frac{7}{2}=3.5$ inches (since the white part is half of the $7$ - inch height of the non - yellow part of the flag).

Step2: Apply the area formula

The area formula for a rectangle is $A = bh$. Substitute $b = 72$ inches and $h=3.5$ inches into the formula. So, $A=72\times3.5 = 252$ square inches.

Answer:

$252$ square - inches
