Answer: A = 18 sq m
Step-by-step explanation:
The area of trapezoid is given by :-
\(\text{Area}=\frac{1}{2}\times(a+b)h\), where and b are the opposite parallel sides and h is the height of the trapezoid.
From the picture, a=8 m, b= 4 m and h=3 m
Now, The area of trapezoid is given by :-
\(\text{Area}=\frac{1}{2}\times(8+4)3\\\Rightarrow\text{Area =}\frac{1}{2}(12)\times3\\\Rightarrow\ \text{Area}=18\ m^2\)
Hence, the area of trapezoid A= 18 sq m.
