Question

The length of the rectangle is 5x²-6 and its breadth is 2x²-2.Find the perimeter

Answer 1

length given = 5x²-6

breadth given = 2x²-2

since , perimeter of a rectangle = 2×(l+b)

perimeter = 2×(5x²-6+2x²-2)

= 2×(7x²-8)

=14x²-16

hence the perimeter of the field is 14x² - 16

hope my answer helps you :)
