Question

identifying area formulas
match each shape with its area formula.
shapes: square, triangle, parallelogram, rectangle
formulas: ( a = lw ), ( a = \frac{1}{2}bh ), ( a = s^2 ), ( a = bh )

Explanation:

Step1: Recall square area formula

A square has side length \( s \), so area \( A = s^2 \).

Step2: Recall triangle area formula

A triangle with base \( b \) and height \( h \) has area \( A=\frac{1}{2}bh \).

Step3: Recall parallelogram area formula

A parallelogram with base \( b \) and height \( h \) has area \( A = bh \).

Step4: Recall rectangle area formula

A rectangle with length \( l \) and width \( w \) has area \( A = lw \).

Answer:

• square: \( A = s^2 \)
• triangle: \( A=\frac{1}{2}bh \)
• parallelogram: \( A = bh \)
• rectangle: \( A = lw \)
