Question

The area of a rectangle is 1764cm square if the length is 4 times ,its bredth , find the length and bredth of a rectangle

Answer 1

Solutions :-


Given :

Area of rectangle = 1764 cm

Let the breadth be x
Therefore, Length = 4x


We know,
Area of rectangle = Length × Breadth

A/q

=> 4x × x = 1764
=> 4x² = 1764
=> x² = 1764/4
=> x² = 441
=> x = √441 = 21



Length = 4x = (4×21) cm = 84 cm
Breadth = x = 21 cm


Hence,
Length and breadth of the rectangle are 84 cm and 21 cm respectively.

Answer 2

HEY MATE HERE IS YOUR ANSWER

_________________________↙️ ↙️

Area of rectangle = 1764 cm

Length of rectangle = x

Breadth of rectangle = 4x

_______________________↙️ ↙️

We know that,

Area of rectangle = L × B ( where L is Length and B is breadth.)

A. T. Q

➡️ 4x × x = 1764

➡️ 4x^2 = 1764

➡️ x^2 = 1764/4

➡️ x^2 = 441

➡️ x = 21 ( because 441 is the square of 21)

=====================================

Length of rectangle = 4 × 21 = 84cm

Breadth of rectangle = 21 cm

=====================================
