Question

The sides of a rectangle
are in the ratio of 4 :3
if the perimeter is 84cm, find
find the measure of it's
length and breadth​

Answer 1

Length : breadth = 4 : 3

perimeter of the rectangle = 84cm.

let, length of the rectangle ( l ) = 4x

breadth of the rectangle ( b ) = 3x

perimeter = 2 ( l + b )

84 = 2 ( 4x + 3x )

》 4x + 3x = 84/2

》 7x = 42

》 x = 42/7

》 x = 6.

Length of the rectangle = 4x = 4 ( 6 ) = 24 cm.

Breadth of the rectangle = 3x = 3 ( 6 ) = 18 cm.

Answer 2

Answer:

Length 24

Breadth 18

Step-by-step explanation:

2 (4x+3x)=84

2×7x=84

14x=84

x=84/14

x=6

4×6=24

3×6=18
