find the area of a parallelogram if a base and corresponding altitude have the indicated lengths base 1 1/2 feet , altitude 6 in
Ostrovityanka [42]

The area of parallelogram is 108 square inches

<em><u>Solution:</u></em>

<em><u>The formula for area of parallelogram is:</u></em>

Area = base \times height

From given,

Base = 1\frac{1}{2}\ feet = \frac{2 \times 1 + 1}{2} = \frac{3}{2}\ feet

Height = 6\ inches

<em><u>Convert feet to inches</u></em>

1 feet = 12 inches

\frac{3}{2}\ feet = \frac{3}{2} \times 12\ inches = 18\ inches

<em><u>Therefore, area of parallelogram is:</u></em>

Area = 18 \times 6\\\\Area = 108

Thus area of parallelogram is 108 square inches
