Which statement about the rectangle with length 9 cm and width 5 cm is true?

Explanation:
Area of a rectangle is found by multiplying its length by its width. With length 9 cm and width 5 cm, the area is 9 × 5 = 45 cm^2, so that statement is true. Perimeter is the distance around the rectangle, computed as 2 × (length + width) = 2 × (9 + 5) = 28 cm, not 18 cm, so that one isn’t correct. The diagonal uses the Pythagorean theorem: diagonal^2 = 9^2 + 5^2 = 81 + 25 = 106, so diagonal = sqrt(106) ≈ 10.3 cm, not 10 cm, so that isn’t correct either.
