Question

A sail is in the form of a right triangle that is four times as high as it is wide. The sail is made from 8 square meters of material. What is the height?

Answer 1

check the picture below

surely you know how much "x" is

so the height is 4x

Answer 2

The height is 8 feet.

Explanation:

The area of a right triangle is given as :

`A=(base* height)/(2)`

We have been given the area as 8 square meters.

Let the base be = b

The sail is four times as high as it is wide, so the height will be = 4b

Putting the values in formula:

`8=(b * 4b)/(2)`

`8=(4b^(2))/(2)`

=>
`4b^(2) =16`

=>
`b^(2) =4`

b=2

So, the base is 2 feet.

And the height will be
`4*2=8` feet.
