Use proportions to find the missing side length (x) in the two similar figures.

Shape 1 (13 yards by x) shape 2 (3.25 yards by 4.23 yards)

4 yards
1.05 yards
9.99 yards
16.92 yards

1 answer

To solve this problem using proportions, we can set up the following equation:

(13 / x) = (3.25 / 4.23)

To isolate x, we can cross-multiply:

13 * 4.23 = 3.25 * x

54.99 = 3.25x

Dividing both sides by 3.25:

x = 54.99 / 3.25

x ≈ 16.92 yards

Therefore, the missing side length (x) in the first shape is approximately 16.92 yards.
