Question

HURRY. Thank you.

A piece of cheese is shaped like a triangle. It has a height of 3.5 inches and a base that is 4.25 inches long. If 1 inch = 2.54 centimeters, find the area of the cheese in square centimeters. Round the answer to the nearest square centimeter.

20 cm2
10 cm2
96 cm2
48 cm2

Answer 1

The answer would be 48 cm2

Explanation:

1. We need to convert the inches to square centimeters.

We multiply 3.5 × 2.54, which is 8.89. We can round this to 8.90.

We also multiply 4.25 × 2.54, which is 10.79500. We can round this to 10.80.

2. The formula to find the area of a triangle is
`a= (hb)/(2)`

3. We plug the numbers into the formula.
`a= ((8.90) (10.80) )/(2)`

4. 8.90 × 10.80 = 96.12

5. 96.12 ÷ 2 = 48.06

6. Round 48.06 to the nearest square centimeter to get 48 cm2
