Find the area of the triangle. 20ft, by 21ft. by 29ft.

a=210ft²

The area of the triangle is 210 square feet.

Step-by-step explanation:

This is a right triangle, as shown by the Pythagorean theorem:

The 2 perpendicular legs of a right triangle are also the base and height of a rectangle of the same size. A right triangle is exactly half of that rectangle, and therefore the area of a right triangle is exactly half of the area of that rectangle.

The area of that rectangle is:

And then the area of the triangle is:

answer: i think it is (1,-2)

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
