The length of a rectangle is 7 cm. The diagonal of the rectangle is 25 cm. What is the ratio of length and breadth of the rectangle?
Show answer & explanation
Correct answer: C
Explanation
Given:
Length = 7 cm
Diagonal = 25 cm
According to the formula:
Diagonal² = Length² + Width²
25² = 7² + Width²
625 = 49 + Width²
Width² = 625 − 49 = 576
Width = 24 cm
Ratio = Length : Width = 7 : 24
