Question

find the area of the parallelogram.
3.98 in
4.21 in
? in²

Explanation:

Step1: Recall the formula for the area of a parallelogram

The area \( A \) of a parallelogram is given by the formula \( A = base \times height \).

Step2: Identify the base and height from the diagram

From the diagram, the base \( b = 4.21 \) in and the height \( h = 3.98 \) in.

Step3: Calculate the area

Substitute the values of base and height into the formula: \( A = 4.21 \times 3.98 \).
Calculating \( 4.21\times3.98 = (4 + 0.21)\times(4 - 0.02)=4\times4-4\times0.02 + 0.21\times4-0.21\times0.02=16-0.08 + 0.84 - 0.0042 = 16.7558 \) (or directly multiply \( 4.21\times3.98 = 16.7558 \)).

Answer:

\( 16.7558 \)
