Answer:
the Diagonal is 41 units
Step-by-step explanation:
Since the sides of a rectangle, to be a rectangle, meet at 90° we use Pythagorean Theorem a² + b² = c²
Width and Length are the legs and the diagonal is the hypotenuse
9² + 40² = c²
81 + 1600 = c²
1681 = c²
√1681 = √c²
41 = c
Answer:
9.52% ( to 2 dec. places )
Step-by-step explanation:
Calculate the percentage increase using
percent increase =
× 100%
increase = 46 - 42 = 4, hence
percent increase =
× 100% ≠ 9.52%
