Question

dear family. in earlier grades, your students learned that a rectangle is a type of parallelogram. one way to find the area of a rectangle is to multiply the length (base) and the width (height) of the rectangle. to find the area of a parallelogram, you can decompose, or break apart, the parallelogram and compose the parts into a rectangle. the base and height of a parallelogram are always perpendicular, forming right angles. the height can be measured inside or outside the parallelogram. your student will be learning how to solve problems like the one below. what is the area of the parallelogram? a = b x h (incorrectly written). one way to find the area is to rearrange the parallelogram into a rectangle. a = l·w = 2.25·2 = 4.5. another way is to use the formula for the area of a parallelogram. a = b·h = 2.25·2 = 4.5. using either method, the area is 4.5 ft².

Explanation:

Step1: Identify the formula

The formula for the area of a parallelogram is $A = b\times h$, where $b$ is the base and $h$ is the height.

Step2: Substitute values

Given $b = 2.25$ ft and $h=2$ ft, we substitute into the formula: $A=2.25\times2$.

Step3: Calculate the result

$2.25\times2 = 4.5$ square - feet.

Answer:

$4.5$ ft²
