Question

vivian’s garage door is shown in the image below. what is the area of vivian’s garage door? the area of vivian’s garage door is blank square ft.

Explanation:

Step1: Split shape into rectangle + trapezoid

The door can be divided into a lower rectangle (width 8ft, height 5ft) and an upper trapezoid (bases 7ft/8ft, height 8-5=3ft).

Step2: Calculate rectangle area

Area = width × height = $8×5=40$ sq ft.

Step3: Calculate trapezoid area

Area = $\frac{(base1+base2)×height}{2} = \frac{(7+8)×3}{2}=22.5$ sq ft.

Step4: Sum areas

Total area = $40+22.5=62.5$ sq ft.

Answer:

62.5
