Answer:

Step-by-step explanation:

1. A=(a+b)*(h/2)

2. A=(4+8)*(3/2)

3. A=12*(3/2)

4. A=12*1.5

5. A=18 sq ft

a=base 1, which is 4 ft

b= base 2, which is 8 ft

h= height, which is 3 ft

Answer:

Area=18 sq. ft

Step-by-step explanation:

Area of a trapezoid [tex]=\frac{a+b}{2} h[/tex]

Area [tex]=\frac{4+8}{2} (3)[/tex]

Area [tex]=\frac{12}{2} (3)[/tex]

Area = 18 sq. ft

choice b.
