Question

the length and breadth of a rectangle are 5x + 2y metres and 2x + y metres respectively. find its perimeter​

Answer 1

Step-by-step explanation:

here,

l= 5x+2y

b= 2x+y

P= 2(l+b)

= 2(5x+2y+2x+y)

=2(7x+3y)

=14x+6y

Answer 2

Answer :

• Perimeter of rectangle is 14x + 6y

Given :

• Length of rectangle = 5x + 2y m
• Breadth of rectangle = 2x + y m

To find :

• Perimeter of rectangle

Solution :

As we know that,

• Perimeter of rectangle = 2(length + breadth)

where , Length is 5x + 2y and breadth is 2x + y

》2(length + breadth)

》2((5x + 2y) +(2x + y))

》10x + 4y + 4x + 2y

》14x + 6y units

Hence , Perimeter of rectangle is 14x + 6y

More Explanation :

• Perimeter of rectangle = 2(length + breadth)
• Area of rectangle = length × breadth
• Diagonal = √(l² + b²)
