Welll....from the diagram, you can see you have two triangles (one on each side)

area of triangle = 1/2 base*height = 1/2 * 2 x 15 = 15ft2 each then you are left with a rectangle 13 ft x 15= 195 ft2

195+15+15=

225 ft2 <----- ANSWER

The area of the parallelogram is equal to 300 square feet.

Given the following data:

  • Width of parallelogram = 20 feet.
  • Base of triangle = 4 feet.
  • Height of triangle = 15 feet.

To calculate the area of the parallelogram:

First of all, we would determine the area of the triangles.

Note: There are two (2) triangles that can be cut-off the given parallelogram.

The formula for the area of a triangle.

Mathematically, the area of the triangle is given by the formula:

[tex]Area=\frac{1}{2} \times base \times height\\\\Area=\frac{1}{2} \times 4 \times 15\\\\Area=2 \times 15[/tex]

Area = 30 [tex]ft^2[/tex]

For the two (2) triangles:

[tex]Area = 2 \times 30[/tex]

Area = 60 [tex]ft^2[/tex]

For the rectangle left:

  • Length = 15 ft.
  • Width = 20 - 4 = 16 ft.

[tex]Area = length \times width\\\\Area = 15 \times 16[/tex]

Area = 240 [tex]ft^2[/tex]

Now, we can calculate the area of the parallelogram:

[tex]Area \;of \;parallelogram = 60 + 240[/tex]

Area of parallelogram = 300 [tex]ft^2[/tex]
