1.	The width of a rectangular hall is \(\frac{3}{4}\) of its length. If the area of the hall is 300 square meter, then the difference between its length and width in meters is1. 32. 43. 54. 12
Answer» Correct Answer - Option 3 : 5 Given: The width of the hall(rectangular) = 3/4 times of its length Area of the hall = 300 m² Formula used: Area of a rectangle = lb l = length of the rectangle; b = width of the rectangle Calculation: b : l = 3 : 4 Let the width be 3x and length be 4x According to the question: lb = 300 ⇒ 12x² = 300 ⇒ x² = 25 ⇒ x = 5 ∴ Difference between length and width of the hall = 4x - 3x = 5 m

The width of a rectangular hall is \(\frac{3}{4}\) of its length. If the area of the hall is 300 square meter, then the difference between its length and width in meters is1. 32. 43. 54. 12

Answer» Correct Answer - Option 3 : 5

Given:

The width of the hall(rectangular) = 3/4 times of its length

Area of the hall = 300 m²

Formula used:
Area of a rectangle = lb

l = length of the rectangle; b = width of the rectangle

Calculation:

b : l = 3 : 4

Let the width be 3x and length be 4x

According to the question:

lb = 300

⇒ 12x² = 300

⇒ x² = 25

⇒ x = 5

∴ Difference between length and width of the hall = 4x - 3x = 5 m
