Find the area of a parallelogram with base length and side length
.
The area of a parallelogram with height
and base
can be found with the equation
. However, while we have been given the length of the base and of another side of the parallelogram, we still do not know the length of the base. Therefore, we do not have enough information to find the area.

Find the perimeter of a parallelogram with a height of , a base of
, and a side of length
.
The perimeter of a parallelogram is the sum of the length of its sides. Since we know the length of the base and of another side, we know that the remaining sides of the parallelogram match those lengths. Therefore:

Compare your answer with the correct one above
What is the area of the trapezoid?
To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.
Compare your answer with the correct one above
What is the area of the above trapezoid?
To find the area of a trapezoid, multiply one half (or 0.5, since we are working with decimals) by the sum of the lengths of its bases (the parallel sides) by its height (the perpendicular distance between the bases). This quantity is

The above diagram depicts a rectangle with isosceles triangle
. If
is the midpoint of
, and the area of the orange region is
, then what is the length of one leg of
?
The length of a leg of is equal to the height of the orange region, which is a trapezoid. Call this length/height
.
Since the triangle is isosceles, then , and since
is the midpoint of
,
. Also, since opposite sides of a rectangle are congruent,
Therefore, the orange region is a trapezoid with bases and
and height
. Its area is 72, so we can set up and solve this equation using the area formula for a trapezoid:
This is the length of one leg of the triangle.
