Answer:
Therefore the length of BC must be 54 meters.
Step-by-step explanation:
Given:
The ratio of the lengths of sides AB : BC
[tex]\dfrac{AB}{BC}=\dfrac{5}{3}[/tex]
AB = 90 meter
To Find:
BC = ?
Solution:
[tex]\dfrac{AB}{BC}=\dfrac{5}{3}[/tex] .................Given
Substituting the values we get
[tex]\dfrac{90}{BC}=\dfrac{5}{3}[/tex]
by Cross multiplying we get
[tex]BC=\dfrac{3\times 90}{5}=\dfrac{270}{5}=54\\\\\therefore BC = 54\ meter[/tex]
Therefore the length of BC must be 54 meters.
