Question

The adjacent sides of the rectangle are $3x^3 - 2xy + 5y^2 and 2x^2 + 5xy - 3y^2$. Find the AREA of the rectangle.

Answer 1

Step-by-step explanation:

Given adjacent sides of a rectangle are 5x 2

-Зу

2

and x

2

+2xy

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

Perimeter=2(5x

2

-Зу

2

)+(x

2

+2xy))

75

=2(6x

2 -Зу

2 +2xy)

2

-6y

2

+4xy

Perimeter=12x

2

-6y

+4xy
