A parallel is a 4-sided shape created by two pairs of parallel lines. The opposite sides are equal in length and opposite angles space equal in measure. To find the area, main point the basic by the height. The formula is:
A = B * H where B is the base, H is the height, and also * means multiply.
The base and height the a parallelogram should be perpendicular. However, the lateral sides of a parallelogram room not perpendicular to the base. Thus, a dotted line is attracted to stand for the height. Let"s look at some instances involving the area that a parallelogram.

Solution:
A = B * H
A = (12 cm) · (5 cm)
A = 60 cm2

Solution:
A = B * H
A = (7 in) · (10 in)
A = 70 in2

Solution:
A = B * H
24 cm2 = (4 cm) · H
24 cm2 ÷ (4 cm) = H
H = 6 cm

A = B * H where B is the base, H is the height, and * means multiply.
