Question

The area of a rectangle in 24 square units. A diagonal drawn from one corner to another divides the rectangle into two right triangles.


What is the area of the shaded triangle?

Answer 1

Hello from MrBillDoesMath!

Answer:

12

Discussion:

The two triangles shown are congruent by the SAS postulate so the area of a single triangle is one-half that of the rectangle.  That is,

Area = (1/2) * 24 = 12

Thank you,

MrB

Answer:

(1/2) * 24 = 12
