The area of the trapezoid ABCD = 37.5 sq. units.

Step-by-step explanation:

If we join points B and D on the figure given with the question.

Then area of the trapezoid ABCD = area of Δ ABD + area of Δ BDC

Now, area of Δ ABD = sq, units.

Again area of Δ BDC = = 25 sq, units

Therefore, the area of the trapezoid ABCD = 12.5 + 25 = 37.5 sq. units.

We know the formula of area of a triangle having vertices , , and will be equal to  

Δ = (Answer)

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
