Question

Ms. Thomas is making a badge for her son in the shape of a square. The sides of the badge measure 3 inches each. Ms. Thomas wants to put a stripe across the badge from one vertex to the other vertex.

What is the approximate length of the stripe?



A.
3.5 inches

B.
4.2 inches

C.
4.9 inches

D.
6.0 inches

Answer 1

You can use pythagorean theorem to find the hypotenuse of the triangle.
Side1^2 + Side2^2 = Hypotenuse^2
So 3^2 is 9. 9+9 is 18 and the square root of 18 comes out to about 4.24 which rounds to 4.2. The answer would be B.
