Question

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

Hello,

The correct answer is 4.

Hope this helps!!!! (:

Answer 2

The answer is: "4" .
______________________________________________________
Note: The question asks for a whole number.

"The area of the triangle above will equal one half of a rectangle that is 5 units long and 4 units wide. (Input only whole numbers, such as 8.).
______________________________________________________
Note: The diagram shows a "right triangle" ; which would be "one-half" of a rectangle, with units of "length" being "5 units" (as mentioned in this very question prompt; and a width of "4" units (as shown in the diagram; hence the answer is "4" units).

Furthermore, the formula/equation for the area, "A" , of a triangle is:


A = (1/2) * b * h ;

that is:

Area = (1/2) * (base length) * (perpendicular height).
_________________________________________________
As such, the answer, "4" (units) makes sense.
