Question

what is the same area in square centimeters?
a 12 cm²
b 6 cm²
c 600 cm²
d 1200 cm²
e 60,000 cm²

Explanation:

Step1: Calculate the area of the triangle in square meters

The formula for the area of a triangle is $A=\frac{1}{2}\times base\times height$. Here, the base is $3m$ and the height is $4m$.
$$A=\frac{1}{2}\times3\times4 = 6m^{2}$$

Step2: Convert square meters to square centimeters

Since $1m = 100cm$, then $1m^{2}=(100cm)\times(100cm)=10000cm^{2}$.
Multiply the area in square meters by $10000$ to get the area in square centimeters.
$$6\times10000 = 60000cm^{2}$$

Answer:

E. $60,000cm^{2}$
