Margo draws a triangle. the lengths of the sides of the triangle are 8", 15" and 17". margo uses the area of 3 squares to show that the triangle is a right triangle. which of these could be the area, in square units, of a square that margo uses?
a. 32
b. 34
c. 46
d. 64

From the given options 64 units is the area of square that Margo used. So, option D is correct.

SOLUTION:

Given, Margo draws a triangle.  The lengths of the sides of the triangle are

Margo uses the area of 3 squares to show that the triangle is a right triangle.  We have to find the area, in square units, of a square that Margo uses . Now, we know that, we can prove a triangle as right angled triangle using Pythagoras theorem  

Assume that above theorem is equation of area of one square = sum area of two squares.  Then, using area of three squares we can prove that a triangle is a right angle triangle.

Now, areas of the three squares will be

the expected value of the random variable : 0, 1 and 2
