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

1.05 meters

Explanation:

Let the length of the rectangular backboard be x

Width = 1.8 m = 180 cm

Area of rectangular backboard =
`Length * Breadth`

Area of rectangular backboard =
`x * 180`

We are given that area is 18,900 sq.cm

So,
`x * 180= 18900`

`x = (18900)/(180)`

`x = 105`

So, length = 105 cm= 1.05 m

Hence the backboard’s length in 1.05 meters
