Question

What is the area of a triangle with a base of 2.4 cm and a height of 0.8 cm? A. 0.96 cm² B. 1.6 cm² C. 1.92 cm² D. 3.2 cm²

Answer 1

The area formula of a triangle is

b×h2 The height of the triangle is 0.8cm. So 0.8cm divided by 2 equals 0.4. 

Now that you know what the height divided by 2 is, you can substitute numbers for variables.

The next thing you need to do is this.

2.4×0.4=? The answer you should get is 0.96...therefore
2.4×0.4=0.96

Does that help?

Answer 2

The area of the triangle should be 0.92.
The answer is A, it being squared.
