Question

Both triangles are similar. The area of the smaller triangle is about 97 ft squared. Which is the best approximation for the area of the larger triangle?

A)144 B)133 C)400 D)190

Answer 1

i got 190?

Answer 2

area of the larger triangle is given by (21/15)^2 *97 = (1.4)^2 *97 =190.12

Answer 3

so best approximation is 190

Answer 4

Because the triangle is a 2-dimensional figure, scaling all of its dimensions by n changes the area by n^2. If you were doing this with a sphere, which is obviously 3-dimensional, the volume would change by n^3.
