Find the area of the parallelogram.

36 ft^2

Step-by-step explanation:

I) Find dimensions:

The length is 9 feet, and the width is 4 feet.

(Remember, 6 ft is not the width because that is the width of the parallelogram's parallel sides.)

II) Find area:

Area = length x width

A = L x W

36 = 9 x 4

III) Find unit:

Make sure to add the unit, it is ft^2 or ft² since this figure is three-dimensional and measured in feet.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
