Question

The area of the triangle above will equal one half of a rectangle that is 5 units long and units wide. (Input only whole numbers, such as 8.) (1 point)

Answer 1

Width of the rectangle is 2

Explanation:

A rectangle can is made up of two right angled triangle as shown.

Since area of a rectangle =
`base * height`

Area of one of the triangle =
`(1)/(2)\ * \ area\ of\ the\ rectangle`

The length and width of the triangle will be the same as that of the rectangle i.e 5units long and 2units wide

Area of one of the triangle =
`(1)/(2) * 5 * 2`

Area of one of the triangle = 5units²

The area of the triangle above will equal one half of a rectangle that is 5 units long and 2 units wide.
