Question

Find the missing side length.

Answer 1

24

Explanation:

In similar shapes, corresponding sides are in the same ratio. Therefore, we can set up the following proportional equation, where "x" is the missing side length:

`x : 30 = 20 : 25`

Express the ratios as fractions:

`(x)/(30)=(20)/(25)`

Multiply both sides by 30 to isolate x:

`(x)/(30)\cdot 30=(20)/(25) \cdot 30`

`x=(20\cdot 30)/(25)`

Carry out the calculation:

`x=(600)/(25)`

`x=24`

Therefore, the missing side length measures 24 units.
