Question

The area of the rectangular garden is 6x²+5x-6. what is the width of the garden if its length is (3x+2)

Answer 1

Answer:

Given adjacent sides of a rectangle are 5x

2

−3y

2

and x

2

+2xy

we know that the perimeter of a rectangle with adjacent sides a and b is 2×(a+b)

Perimeter=2((5x

2

−3y

2

)+(x

2

+2xy))

=2(6x

2

−3y

2

+2xy)

=12x

2

−6y

2

+4xy

∴Perimeter=12x

2

−6y

2

+4xy
