Question

A rectangle can be divided evenly into two right triangles. If the area of the rectangle below is 60 units2, what is the area of the blue right triangle?

Answer 1

`30\text{ unit}^2`

Explanation:

GIVEN: A rectangle can be divided evenly into two right triangles. If the area of the rectangle is
`60`
`units^2`.

TO FIND: area of the blue right triangle.

SOLUTION:

As the rectangle is divided between two even right triangle area of both right triangle is equal.

let the area of one right triangle
`=x\text{unit}^2`

As the sum of area of triangles s equal to area of rectangle

`x+x=60\text{ units}^2`

`2x =60`

`x=(60)/(2)`

`x=30\text{ unit}^2`

Hence the area of one of the right triangle is
`30\text{ unit}^2`
