Question

the length of a rectangle exceeds it's a breath by 4m. if the perimeter of the rectangle is 84 metres.find the length and breadth s

Answer 1

Hello here is your answer by Sujeet yaduvanshi ☝☝☝☝☝☝☝☝☝☝


GIVEN That:-

Perimeter of Rectangle:- 84m

then,

Let to be Breadth x

Therefore:-

Length will be (x+4)

According to the question..

2(l+b)=84 m
here,


Length:- L
Breadth:- B


2(x+4+x)=84
2(2x+4)=84
2x+4=84/2
2x+4=42

2x=42-4

2x=38

x=38/2

x=19

then,

Length=19+4=23
Breadth=19

that's

Answer 2

STEP 1: Define Length and Breadth:

Let the breadth be x

The length = x + 4

....................................................................................

STEP 2: Form equation:

Perimeter = 2 ( Length + Breadth)

2 ( x + x + 4 ) = 84

2 (2x + 4) = 84

4x + 8 = 84

4x = 76

x = 19

.....................................................................................

STEP 3: Find length and breadth:

Breadth = x = 19

Length = x + 4 = 19 + 4 = 23

.....................................................................................

Answer: The length is 23 m and the breadth is 19 m
