Answer 1

Given:

Height, h = 4 ft

Top base = 8 ft

Bottom base = 2 ft + 8 ft + 2 ft = 12 ft.

Let's find the area of the banner.

Here, the banner has the shape of a traezoid.

To find the area, apply the formula for the area of a trapezoid:

`A=(a+b)/(2)* h`

Where:

A is the area

a is the top base = 8 ft

b is the bottom base = 12 ft

h is the height = 4 ft

Plug in values in the formula and solve for A:

`\begin{gathered} A=(8+12)/(2)*4 \\ \\ A=(20)/(2)*4 \\ \\ A=10*4 \\ \\ A=40ft^2 \end{gathered}`

Therefore, the area of the banner is 40 square feet.

ANSWER:

40 ft²
