A triangle with an area of 3 mm² is dilated by a factor of 6. What is the area of the dilated triangle? 9 mm² 12 mm² 18 mm² 108 mm²
Question
Answer:
By definition, the area of a triangle is given by:A = (1/2) * (b) * (h)
Where,
b: base
h: height
The area of the original triangle is 3 mm² and is dilated by a factor of 6. We have then
A = (1/2) * (6b) * (6h)
A = (1/2) * (b) * (h) * (6) * (6)
A = 3 * (6) * (6)
A = 108 mm²
answer
The area of the dilated triangle is 108 mm²
