Answer:
The area of trapezoid is 48 m².
Step-by-step explanation:
You have to apply the area of trapezoid formula, A = 1/2×(a+b)×h where a and b represents the length and h is the height :
[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]
[tex]let \: a = 3,b = 9,h = 8[/tex]
[tex]area = \frac{1}{2} \times (3 + 9) \times 8[/tex]
[tex]area = \frac{1}{2} \times 12 \times 8[/tex]
[tex]area = 48 \: {m}^{2} [/tex]
