Question:

What is the area of an isosceles right triangle that has one leg that measures 4 cm?

A 8 cm
Explaination

If the triangle is isosceles, that means its two legs are equal in length, so they are both 4. In a right triangle, the two legs are the base and the height. The area of a triangle is equal to $7435_w29_h37.png$, so the area =$6810_w106_h37.png$cm.
