Question

What is the area of the trapezoid below? The diagram is not drawn to scale.
The choices are:
a. 60 cm^2
b. 85 cm^2
c. 12 cm^2
d. 30 cm^2

Answer 1

the formula is ( h/2) * (a+b)

where a and b are the lengths of the parallel lines and h = height

Answer 2

the trickiest part is the length of the base
since the 2 angles are equal the 2 end parts are both 5 cm
so length of b = 10+7 = 17

Answer 3

a = 7 and h = 5

so plug these values into the formula to get the area
