Given:
Length of the parallelogram = 25 feet
Width of the parallelogram = 20 feet
Perpendicular distance from the long side to the opposite long side = 18 feet.
To find:
The area of the piece of land which is a parallelogram.
Solution:
Area of a parallelogram:
[tex]Area=Base\times height[/tex]
Let the longer side, 25 feet is the base, then the height of the parallelogram is 18 feet. So, the area of the parallelogram is
[tex]Area=25\times 18[/tex]
[tex]Area=450[/tex]
Therefore, the area of the piece of land is 450 square feet.
