Question

How can you use the formula for area of a
parallelogram to determine the area of a trapezoid if you forgot the
formula for area of a trapezoid.

Answer 1

Answer:

Step-by-step explanation:

The area of a parallelogram of width W and length L is A = W*L.

The area of a trapezoid of width W and different side lengths L1 and L2 is

A = W(L1 + L2)/2.  

To find the area of the trapezoid, take the average of the lengths L1 and L2 of the two parallel sides and call the result L.  Then apply the formula for the area of a parallelogram, given above).
