Question

The height of a television screen varies with its width. A television screen is 60cm wide and 33.75cm high. What is the height of a screen that is 90cm wide?

Answer 1

The height of the screen that 90 cm wide is 50.625 cm

Explanation:

Given as :

The height of television varies with its width

The Width of the television screen =
`w_1` = 60 cm

The height of the television screen =
`h_1` = 33.75 cm

Again ,

The height of the television screen =
`h_2`

Let The Width of the television screen =
`w_2` = 90 cm

∵ The height of television varies with its width

So,
`(h_2)/(h_1)` =
`(w_2)/(w_1)`

Or,
`(h_2)/(33.75)` =
`(90)/(60)`

Or,
`h_2` = 1.5 × 33.75

∴
`h_2` = 50.625 cm

Hence The height of the screen that 90 cm wide is 50.625 cm Answer
