Use the formula for the area of a parallelogram.

About 3.7cm^2

Practice makes perfect

Let's consider the given parallelogram.

We want to find the area of the parallelogram. We can use the following formula to do it. Area= b h In this formula, b is the length of the base and h is the height. For our parallelogram, we will substitute b= 2.3 for the base and h= 1.6 for the height into the formula to calculate its area.

Area=bh

SubstituteII

b= 2.3, h= 1.6

Area= 2.3( 1.6)

Multiply

Area=3.68

RoundDec

Round to 1 decimal place(s)

Area≈ 3.7

The area of the parallelogram is about 3.7 square centimeters.
