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

Answer:

1.05 m

Step-by-step explanation:

The area of the rectangular backboard is A = 18900 cm²

And the width is w = 1.8 m = 1.8 ×100 = 180 cm

The area of the rectangle is given by

[tex]A=l\cdot w[/tex]

Substituting the known values

[tex]18900=l\cdot 180\\\\l=\frac{18900}{180}\\\\l=105\text{ cm}[/tex]

Thus, the length of the backboard's is 105 cm = 1.05 m
