Question

Craig takes a rectangular piece of fabric and makes a diagonal cut from one corner to the

opposite corner. The cut he makes is 20 centimeters long and the width of the fabric is 12
centimeters. What is the fabric's length?

Answer 1

16 cm

Explanation:

We can use the Pythagorean Theorem for this: a^2 + b^2 = c^2

12^2 + b^2 = 20^2

144 + b^2 = 400

b^2 = 256

b = 16 cm
