Answer:
18 m^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 5 + (6+1)) * 3
A = 1/2 ( 5+7)*3
= 1/2 (12)3
= 18
B
greater base = 6 + 1 = 7 m
Area = [(greater base + minor base) * height] / 2 = [(7+5) * 3]/2 =18 m^2
