Question

the length and breadth of a rectangle are (4x²+5y-3)cm and (3x²-2y+2)cm find the perimeter of rectangle​

Answer 1

Answer:

The answer is 14x²+6y-2

Step-by-step explanation:

Perimeter=2(length+breadth)

2(4x²+5y-3+3x²-2y+2)

2(7x²+3y-1)

14x²+6y-2

Hope it will help you

Answer 2

$\large\sf \underline{ Given:}$

• Length=4x²+5y-3
• Breadth=3x²-2y+2

$\large \sf \underline{To \: find:}$

• Perimeter of rectangle

$\sf \large \underline{Solution:}$

Perimeter of rectangle=2(l+b)

⇨2[4x²+5y-3+(3x²-2y+2)]

⇨2[4x²+5y-3+3x²-2y+2]

⇨2[7x²+3y-1]

⇨14x²+6y-2

divide this equation by 2

⇨7x²+3y-1

This is the answer or you can also factorise this equation.

$\large \sf \underline{Formula \: used:}$

Perimeter of rectangle=2(L+B)

Where L and B are length and breadth of rectangle.
