Question

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

Answer 1

Answer:

14x2-14y+2 this is the answer and the formula is 2× length + breadth

Answer 2

Given : Length of rectangle = (4x² + 5y - 3)cm

            Breadth of rectangle = (3x² - 2y + 2)cm

To Find: Perimeter of rectangle = ?

• Solution: We know that,
• Perimeter of Rectangle = 2(length + breadth)
•                                         = 2[ (4x² + 5y - 3) + (3x² - 2y + 2)]
•                                         = 2(7x² + 3y - 1)
•                                         = 14x² + 6y - 2
• Hence, the perimeter of rectangle is (14x² + 6y -2)cm.
