The dimensions of triangle B are three times the dimensions of triangle A. The area of triangle A is 4.5 cm2.
What is the area of triangle B?
A.
13.5 cm2
B.
20.25 cm2
C.
40.5 cm2
D.
9 cm2
The area of triangle B can be found by squaring the multiplier (3) and then multiplying by the area of triangle A.
Area of triangle B = (3^2) * 4.5 = 9 * 4.5 = 40.5 cm^2
Therefore, the area of triangle B is 40.5 cm^2.
Correct answer: C. 40.5 cm2
