The breadth of a rectangular hall is 8/3 of its length. The area of the floor is 96 square metre, then what is the difference (in metre) between the length and breadth of the hall?
Show answer & explanation
Correct answer: B
Explanation
Given:
Width = (8/3) × Length
Area = 96 square meters
According to the formula:
Area = Length × Width
Let Length = x
Width = (8/3)x
x × (8/3)x = 96
(8/3)x² = 96
x² = (96 × 3)/8 = 36
x = 6
Width = (8/3) × 6 = 16
Difference = 16 − 6 = 10
