Question

Wnen 5 is subtracted from length and breadth of the rectangle, the perimeter becomes 26cm
What is the mathematical form of the statement?

​

Answer 1

hey mate!

Let length be (l-5)

and breadth be (b-5)

Perimeter of a rectangle is 2(l+b)

so, mathematical form of statement is :

2 [(l-5)+(b-5)] = 26, also written as

2[ l-5+b-5 ] = 26

hope this helps you

pls mark it as brainliest

thanks❤❤

Answer 2

Answer:

• Mathematical form of the statement is x+y = 23.

Given:

• 5 is subtracted from length and breadth of the rectangle.
• Perimeter of rectangle = 26cm.

To Find:

• Mathematical form of the statement = ?

Solution:

According to the question, 5 is subtracted from length and 5 is subtracted from breadth and perimeter of rectangle is 26cm and we are said to find mathematical form of the statement.

Let's assume:

• Let the length be x-5.
• Let the breadth be y-5.

As we know,

$\sf\large\boxed{Perimeter \:of \: rectangle = 2 (l + b)}$

where,

• l is length.
• b is breadth.

According to the question,

•Perimeter of rectangle = 26cm

•2(x-5 + y-5) = 26cm

Let's take common number at both sides

•x + y -10 = 13

•x + y = 13 +10

•x + y = 23

Hence, mathematical form is x+y = 23.
