How do you find the ratio if the areas of 2 similar triangles in which the ratio of a pair of corresponding sides is 4:1

for similar shapes the ratio of areas is equal to the ratio of squares of the corresponding sides

since the sides are 4 : 1
the areas have a ration of 16: 1

To find the ratio of the areas of two similar triangles, you need to square the ratio of their corresponding sides.

Here's how to do that:

1. Start with the given ratio of the corresponding sides of the triangles. In this case, the ratio of a pair of corresponding sides is 4:1.

2. Square the ratio. In this case, the square of 4:1 is (4^2):(1^2) = 16:1.

3. The ratio you obtained in step 2 represents the ratio of the areas of the two similar triangles. In this case, the ratio of the areas is 16:1.

Therefore, the ratio of the areas of the two similar triangles is 16:1.
