If I have two different units of measurement and I multiply them which unit would I convert it to? For example: I want to find the area of a triangle (1/2 bxh) The height (h) is 55 cm. The base (b) is 1.8m 55x1.8= 99. I've halved it (49.5) but don't know what unit to make it.

4950 cm ^ 2  or 0.495 m ^ 2

Step-by-step explanation:

You must pass both units to the same unit. That is, you can multiply either cm * cm to make it cm ^ 2 or m * m to make it m ^ 2, but cm * m just can't.

In this case, you can pass the base 1.8 m to cm, knowing that 1 m equals 100 cm, therefore:

1.8m * 100cm / 1m = 180cm

now if you can calculate the area

55 * 180/2 = 4950 cm ^ 2

Or you can also pass the height in meters, with the same conversion above:

55cm * 1m / 100cm = 0.55m

replacing that:

0.55 * 1.8 / 2 = 0.495 m ^ 2

Although the number is different, the area is still the same, but in one case it is in cm ^ 2, which is a unit smaller than m ^ 2.

b. 13

step-by-step explanation:

as there are 13 students in bowling class therefore the most reasonable answer is b as only 13 students are in the bowling class.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
