Question

match the formula for each area to the figure to which it applies.
figure\t\tarea
☑ square
a. $a = \frac{1}{2}bh$
☑ rectangle
b. $a = s^2$
☑ circle
c. $a = lw$
☑ triangle
d. $a = \pi r^2$

Explanation:

Step1: Recall Square Area Formula

A square has side length \( s \), so its area is \( A = s^2 \), which matches option b.

Step2: Recall Rectangle Area Formula

A rectangle has length \( l \) and width \( w \), so its area is \( A = lw \), which matches option c.

Step3: Recall Circle Area Formula

A circle has radius \( r \), so its area is \( A=\pi r^2 \), which matches option d.

Step4: Recall Triangle Area Formula

A triangle has base \( b \) and height \( h \), so its area is \( A = \frac{1}{2}bh \), which matches option a.

Answer:

Square: b. \( A = s^2 \)
Rectangle: c. \( A = lw \)
Circle: d. \( A=\pi r^2 \)
Triangle: a. \( A = \frac{1}{2}bh \)
