What is the area of the trapezoid?
Alecsey [184]

Area of trapezoid:

A = 1/2(b1+b2)h

where

b1 = 30,

b2 = 28+12 = 40


Triangle FOG

a^2 = c^2 - b^2

a^2 = 13^2 - 12^2

a^2 = 169 - 144

a^2 = 25

a = √25

a = 5


FO = 5 so height h = FO = 5

Now you can find the Area of trapezoid

A = 1/2(b1+b2)h

A = 1/2(30 + 40) (5)

A = 1/2(70)(5)

A = 175


Answer

175 square units

6.perimeter of the given shape above is
avanturin [10]
The answer is B.

One side is 14 feet and the other is 6. Since it is a rectangle and a rectangle has four sides, we need to take 14 and multiply it by 2. That will get us 28. Same thing apply for the other side. 6 multiplied by 2 is 12. And if we take our 2 numbers which are 28 and 12 and we add them up, our Perimeter is 40.

Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time, and good luck finding the correct answer :)
