Find the area of the irregular figure. Round to the nearest hundredth.

Step-by-step explanation:

The composite figure consists of one rectangle and two triangles. We can add up the area of these individual shapes to find the total area of the irregular figure.

Formulas:

By definition, the base and height must intersect at a 90 degree angle.

The rectangle has a base of 10 and a height of 5. Therefore, its area is .

The smaller triangle to the left of the rectangle has a base of 2 and a height of 5. Therefore, its area is .

Finally, the larger triangle on top of the rectangle has a base of 5 and a height of 5. Therefore, its area is .

Thus, the area of the total irregular figure is:

the answer to this question is in the pic
