Question

(05.01 LC)

A right triangle ABC is shown below:

A right triangle ABC with height AB labeled 4 units and base BC labeled 5 units is shown.

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.)

Answer 1

ITS 3

Explanation:

Answer 2

The Rectangle is 2 units wide

Explanation:

Given as , A Right angle Triangle ABC

The height of Triangle AB = 4 units

The Base Of Triangle BC = 5 units

SO, The Area of Triangle =
`(1)/(2)* Height * Base`

Or, The Area of Triangle =
`(1)/(2)* AB * BC`

Or, The Area of Triangle =
`(1)/(2)* 4 unit * 5 unit`

Or, The Area of Triangle = 10 units

Now , As per question :

The Area of Triangle = The Area of Rectangle

∵ length of Rectangle be L

And width of Rectangle be W

So , The Area of Triangle = The Area of Rectangle

Or, 10 units = L × W

Or, 10 units = 5 units × W

∴ Width of Rectangle =
`(10)/(5)` = 2 units

Hence the Rectangle is 2 units wide Answer
