A square is cut in half on the diagonal creating two equal triangles each triangle has an area of 0.72 square units what is the
Katyanochek1 [597]

In a square all 4 sides are equal, so when you cut it along the diagonal to make a triangle, both the base and the height of the triangle would be the same.


The area of a triangle is found by the formula 1/2 x base x height

Since the base and height are the same the formula becomes Area = 1/2 x S^2 ( where S is the length of a side).

The area is given as 0.72 square units.

Now you have 0.72 = 1/2 x S^2

First multiply both sides by 2:

1.44 = S^2

To find S, take the square root of both sides:

S = √1.44

S = 1.2

The side length is 1.2 units.

What are the coordinates of the points (2,-3) after a counter clockwise rotation of 90 about the Origin?
Ber [7]

Step-by-step explanation:

(2, -3) is in the 4th quadrant. By the counter clockwise rotation of 90° around the origin, it will be in the 1st quadrant.

Any point in the 1st quadrant has both positive x and y coordinates.

So the answer is (3, 2).
