Question

in this activity you will:

• find the area of a parallelogram, triangle, trapezoid, and circle.
• determine population if given area and density.

value: 2

what shapes use the area formula a = lw?

a. triangle
b. rectangle
c. trapezoid
d. parallelogram

Explanation:

The formula $A = lw$ represents the area of a rectangle, where $l$ is the length and $w$ is the width. A triangle has area formula $A=\frac{1}{2}bh$, a trapezoid has $A=\frac{1}{2}(a + b)h$ and a parallelogram has $A = bh$.

Answer:

B. Rectangle
