Finding the Ratio of Triangle Areas

To find the ratio of the areas of two triangles, we need to know the lengths of their corresponding sides. In this case, we have the lengths of the sides of one triangle and the ratio of the sides of the other triangle.

Let's denote the sides of the first triangle as a, b, and c, and the sides of the second triangle as x, y, and z. We are given that the sides of the first triangle are 24 cm, 42 cm, and 54 cm, respectively. The sides of the second triangle are in the ratio of 9:4:7, and the length of its largest side is 108 cm.

To find the lengths of the sides of the second triangle, we can set up the following proportion:

x:y:z = 9:4:7

Since the largest side of the second triangle is 108 cm, we can set up the equation:

z = 108

To find the values of x and y, we can use the fact that the sides are in the ratio of 9:4:7. Let's assume that the common ratio is r:

x = 9r y = 4r

Now we can substitute these values into the equation x + y + z = 108:

9r + 4r + 108 = 108

Simplifying the equation, we get:

13r = 0

Since r cannot be zero, this equation has no solution. Therefore, the given information is inconsistent, and we cannot determine the ratio of the areas of the two triangles.
