The length of a rectangle is 7 units and its width is 5 units. What is the approximate length of the diagonal of the rectangle? (5 points)
4.9 units
6 units
8.6 units
9 units

Answer 1

Just need to apply Pythagora's Theorem:

a² + b² = c²

Where a and b are the sides, and c is the diagonal, therefore:

7² + 5² = c²

49 + 25 = c²

c = √(74)

c = 8.6

Answer: 8.6 units
