perimeter of rectangle is 24 meter If length of a rectangle is 2meter more then breadth then find the breadth of rectangle
Answers
Answer:
perimeter of rectangle= 2( l+b)
length= 2+b and breadth= b
24=2(2+b+b)
12=2+2b
10= 2b
b= 5 metres
Given:
✰ A perimeter of rectangle = 24 m
✰ The length of a rectangle is 2 m more than breadth.
To find:
✠ The breadth of rectangle.
Solution:
Let's understand the concept first! We will calculate the breadth of rectangle by using formula of perimeter of rectangle. First we will assume that the breadth of a rectangle as x and we know that the length of a rectangle is 2 m more than breadth i.e, we will add 2 to its breadth which is equal to it's length ( x + 2 ).
Let's find out...✧
Let the breadth of a rectangle be x.
Then, the length of a rectangle be x + 2.
✭ Perimeter of a rectangle = 2 ( l + b ) ✭
➤ 24 = 2 ( 2 + x + x )
➤ 24 = 2 ( 2 + 2x )
➤ 24 = 4 + 4x
➤ 4x = 24 - 4
➤ 4x = 20
➤ x = 20/4
➤ x = 5
∴ The breadth of rectangle = 5 m
What if we need to find the length of rectangle?
Let's find out..
➛ The length of rectangle = x + 2
➛ The length of rectangle = 5 + 2
➛ The length of rectangle = 7 m
