A. 8.45 m² paint will be required to paint the front of the garage except the area of the rectangle door.
B. 4 cans of paint required to paint the front of the garage.
C. The cost to paint the front of the garage is $98.
What is the area of a rectangle?
The area of a rectangle is the total area covered by that rectangle.
The area of a rectangle = length × width.
We need to find the area of the front of the garage except the door.
The area of the door = width × height = 2 × 1.5 m² = 3 m².
Therefore, the area to be painted
= front area of the garage - the area of the door
= [(3.5 × 2.5) + ([tex]\frac{1}{2}[/tex] × 3.5 ×1.2) - 3] m²
= [8.75 + 2.1 - 3] m²
= 7.85 m²
If a can has 2.5 m² paint, then the total number of cans required
= [tex]\frac{7.85}{2.5}[/tex]
= 3.14
≈ 4.
A can costs $24.50, then the total cost to paint the front of the garage
= 4 × $ 24.5
= $ 98
