Question

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

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 2

1.05 m

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

`A=l\cdot w`

Substituting the known values

`18900=l\cdot 180\\\\l=(18900)/(180)\\\\l=105\text{ cm}`

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