Question

If Breadth = 27, Perimeter = 156, then find Length of the rectangle.

Need full explanation. ​

Answer 1

Answer:

51

Step-by-step explanation:

let length be x

then,2(x+27)=156

2x+54=156

2x=156-54

x=102÷2=51

hence required length =51

Answer 2

Given :

• Breadth of rectangle = 27 m
• Perimeter of rectangle = 156 m

To find :

• Length of rectangle

According to the question,

Let the length of rectangle be x

➞ Perimeter of rectangle = 2 (length + breadth)

➞ 156 = 2(x + 27)

➞ 156 = 2x + 54

➞ 156 - 54 = 2x

➞ 102 = 2x

➞ 102 ÷ 2 = x

➞ 51 = x

• So,the length of rectangle is 51 m.

★ Verification ★

➞ Perimeter of rectangle = 2(length + breadth)

➞ Perimeter of rectangle = 2(51 m + 27 m)

➞ Perimeter of rectangle = 2(78 m)

➞ Perimeter of rectangle = 156 m

.°. L.H.S = R.H.S

Hence,verified.
