1.	The length of a rectangle is four times of its breadth, If the area of the rectangle is 1764 cm2, then what is the length of the rectangle?1. 212. 843. 444. 56
Answer» Correct Answer - Option 2 : 84 Given: The area of the rectangle = 1764 cm2 Formula used: Area of rectangle = length × breadth Calculation: Let the breadth of the rectangle be x then its length is 4x Area = length × breadth ⇒ 4x × x = 1764 ⇒ x² = 441 ⇒ x = 21 Length of the rectangle = 4 × 21 = 84 cm ∴ The length of the rectangle is 84 cm

The length of a rectangle is four times of its breadth, If the area of the rectangle is 1764 cm2, then what is the length of the rectangle?1. 212. 843. 444. 56

Answer» Correct Answer - Option 2 : 84

Given:

The area of the rectangle = 1764 cm2

Formula used:

Area of rectangle = length × breadth

Calculation:

Let the breadth of the rectangle be x then its length is 4x

Area = length × breadth

⇒ 4x × x = 1764

⇒ x² = 441

⇒ x = 21

Length of the rectangle = 4 × 21 = 84 cm

∴ The length of the rectangle is 84 cm
