Question

d the area of each triangle.

Explanation:

Step1: Recall rectangle area formula

The area formula for a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.
For the first rectangle with length $l = 13.6$ and width $w=12.2$, we have $A_1=13.6\times12.2 = 165.92$.
For the second rectangle with length $l = 9.6$ and width $w = 14.1$, we have $A_2=9.6\times14.1=135.36$.

Step2: Recall triangle area formula

The area formula for a triangle is $A=\frac{1}{2}\times b\times h$, where $b$ is the base and $h$ is the height.
For the first triangle with base $b = 3.2$ and height $h = 8.5$, we have $A_3=\frac{1}{2}\times3.2\times8.5=13.6$.
For the second triangle with base $b = 2.2$ and height $h = 5.6$, we have $A_4=\frac{1}{2}\times2.2\times5.6 = 6.16$.

Answer:

The area of the first rectangle is $165.92$, the area of the second rectangle is $135.36$, the area of the first triangle is $13.6$, and the area of the second triangle is $6.16$.
