What is the area of the trapezoid shown below?​
Olin [163]

Answer:

78 sqr units

Step-by-step explanation:

Use the Pythagorean Theorem to help find the base opposite the two.

The base of the second parallel line is sqrt(  (15^2) - (12^2)  ) = sqrt(81) = 9

The second base = 9 + 2 = 11

Area = (b1 + b2)*h/2

h = 12

b1 = 2

b2 = 11

h = 12

Area = (11 + 2)*12/2

Area = 13 * 12/2

Area = 78 square units

Alex777 [14]

Yes absolutely as if you just take a circle and break the circle from the centre point into pieces such that the no

of pieces formed is infinite and and then when you take the pieces of the circle and arrange them in the form of rectangle then the area of the rectangle obviously equal to the area of circles.For better understanding I had attached a picture with the answer
