Verified Answer :

Area of a trapezoid is A=height over 2 B1 +B2, so 10+10=20, then 20(8)=160, 160/2=80. Answer is b.

Answer:

Step-by-step explanation:

Alright, lets get started.

The given two sides are AB = 10

CD = 10

It means a is 10 and b is 10.

The height h is given as 8.

The formula of area of trapezoid = \(\frac{1}{2}(a+b)*h\)

Plugging the values of a,b and h in the formula:

area = \(\frac{1}{2}(10+10)*8\)

area = \(\frac{1}{2}*20*8\)

area = \(10*8=80\)

Hence the area is 80 units  :  Answer B
