The rectangular backboard of a basketball court needs to be assembled. Its area is given as 18,900 cm2 and the width as 1.8 m.What is the backboard’s length in metres?

Answer: 
1.05

Explanation: 
The formula for area is:
A = l • w 
So to find the length, you would rearrange to make:
l = A ÷ w 
1.8 m = 180 cm 
So: 
l = 18,900 ÷ 180 
l = 105 cm 
105 cm = 1.05 m
