Calculate the area and perimeter of a parallelogram:
Calculate the area and perimeter of a parallelogram with base (b) = 4´, height (h) = 3´, a = 5´ and b = 4´. Be sure to include units in your answer.
Solution:
A = bh P = 2a + 2b
A = (4)(3) P = 2(5) + 2(4)
A = 12 square feet P = 10 + 8
P = 18 feet
A rectangle is a parallelogram along with four right angles, as display in Figure.
Figure: Rectangle
The area of a rectangle is computed using the subsequent formula:
A = (length) (width) = lw
The perimeter of a rectangle is calculated using the following formula:
P = 2(length) + 2(width) = 2l + 2w
An area of a rectangle is always expressed in square units, and the perimeter of a rectangle is always expressed in the original units.
