Question

A triangle has a side length of 4 inches and an area of 18 square inches and a larger similar triangle has a corresponding side length of 8 inches. Find the area of the larger tringle ?
...?

Answer 1

For this problem, we can use ratio since these triangle are said to be similar triangles. We calculate as follows:

L1/A1 = L2/A2
4/18 = 8/A2
2/9 = 8/A2
A2 = 36 square inches

The area of the larger triangle would be 36 square inches. Hope this answers the question. Have a nice day.
