Question

The perimeter of rectangle is 130 cm. if the breadth of the rectangle is 30cm,find its length.

Answer 1

Step-by-step explanation:

given: perimeter of the rectangle= 130

breadth= 30

length=?

perimeter of rectangle = 2(l+b)=130

2(l+30)=130

l+30 = 130/2

l+30= 65

l= 65-30

l= 35

therefore the length of the rectangle is 35

Answer 2

Answer:

Given breadth of the rectangle = 30cm

Given perimeter of the rectangle = 130cm

Length of the rectangle = ?

We know that perimeter is equal to 2(l + b). So, by substituting the values, we will get the measure of the length.

⇒ Perimeter of the rectangle = 2(l + b)

⇒ 130cm = 2(l + 30)

⇒ 130/2 = l + 30

⇒ 65cm = l + 30

⇒ 65cm - 30 = l

⇒ 35cm = l

∴ The length of the rectangle is 35cm

Thnx and have a nice day!
