# Display case

Place a glass shelf at the height of 1m from the bottom of the display case in the cabinet. How long platter will we place at this height?

The display case is a rectangular triangle with 2 m and 2.5 m legs.

Result

x =  1.2 m

#### Solution:

$2.5:2=(2.5-1):x \ \\ x=(2.5-1) \cdot \ \dfrac{ 2 }{ 2.5 }=\dfrac{ 6 }{ 5 }=1.2 \ \text{m}$
