Question

the perimeter of a rectangle is 50 M the breath is 10 M less than the length of a rectangle find the length and breadth of a rectangle

Answer 1

Hi friends
Here is your answer

Let the length is x m
So Breadth is x - 10

Perimeter = 2( L + B)
$50 = 2(x + x - 10) \\ \\ \frac{50}{2} = 2x - 10 \\ \\ 2x = 25 + 10 \\ \\ x = \frac{35}{2} \\ \\ x = 17.5 \: m$
Therefore
Length is 17.5 m
Breadth is 17.5 - 10 = 7.5 m

Hope it helps you

Answer 2

Given that:

• The perimeter of a rectangle is 50 m.
• The breadth is 10 m less than the length of a rectangle.

To Find:

• Its length and breadth.

Let us assume:

• The length of the rectangle be x.
• Breadth = x - 10

Formula used:

• Perimeter of a rectangle = 2(Length + Breadth)

Finding its length and breadth:

According to the question.

ㅤ↠ㅤ50 = 2(x + x - 10)

ㅤ↠ㅤ2(25) = 2(2x - 10)

Cancelling 2 both sides.

ㅤ↠ㅤ25 = 2x - 10

ㅤ↠ㅤ2x = 25 + 10

ㅤ↠ㅤ2x = 35

ㅤ↠ㅤx = 35/2

ㅤ↠ㅤx = 17.5

Hence,

• Length = x = 17.5 m
• Breadth = x - 10 = 17.5 - 10 = 7.5 m
