Question

find the area of each triangle to the nearest tenth.

Answer 1

Answer:

9. 60.5 cm 10. 30 mi

Step-by-step explanation:

The equation for the area of a triangle is:

Base×Height÷2

9.

1. plug in the numbers with Base×Height÷2: 11×11÷2

2. solve: 11×11=121

3. 121 ÷ 2 = 60.5

Answer: 60.5 cm

10.

1. plug in the numbers with Base×Height÷2: 5×12÷2

2. solve: 5×12= 60

3. 60÷2=30

Answer: 30 mi

Answer 2

9. Area = 59.755$cm^{2}$ square cm. when the area to nearest tenth then, area = 60 square cm.

10. Area = 22.9813$mi^{2}$. When the area to nearest tenth then, area = 20 square mi.

Area of the Triangle:

Area of the triangle is = half of (base x height)

=> (1/2) x (b x h)
