Question

1. which of the following could be the first step to correctly computing the area of the triangle below? select all that apply. 0.6 m 40 cm a. multiply 0.6 by 40. b. add 40 and 0.6 together. c. convert 0.6 m to centimeters. d. convert 40 cm to meters and 0.6 m to centimeters. e. convert 40 cm to meters.

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ and $h$ are the base and height. For this formula to be used correctly, the base and height must be in the same - unit of measurement.

Step2: Analyze units

The height is given as $0.6$ m and the base as $40$ cm. Since the units are different, the first step is to make the units consistent.

Answer:

C. Convert 0.6 m to centimeters; E. Convert 40 cm to meters
