Answer:
100 cm^2
Step-by-step explanation:
The area of the trapezoidal shape of the shaded area is given by the formula ...
A = (1/2)(b1 +b2)h
where b1 and b2 are the base lengths (6 cm, 14 cm) and h is the height (10 cm). Filling in the numbers gives you the area as ...
A = (1/2)(6 cm + 14 cm)(10 cm) = 100 cm^2
The shaded area is 100 cm^2.
