Find the areas of the trapezoids
Gennadij [26K]

Answer:

figure 1 - 10.5 unit^2

figure 2 - 12 unit^2

Step-by-step explanation:

<u>figure 1</u>

1. find the area of the rectangle

<em>3*2 = 6 unit^2</em>

2. find the area of the triangle

<em>(3*3)/2 = 4.5 unit^2</em>

3. add the area of the rectangle and the area of the triangle together. The sum would be the area of the trapezoid.

<em>6 + 4.5 = </em><u><em>10.5 unit^2</em></u>

<u>figure 2</u>

1. find the area of the rectangle

<em>2*4 = 8 unit^2</em>

2. find the area of both triangles

<em>(1*4)/2 = 2 unit^2</em>

3. add the area of the rectangle and the area of both triangles together. The sum would be the area of the trapezoid.

<em>8 + 2 + 2 = </em><u><em>12 unit^2</em></u>
