Question

The sides of a rectangle are given by x2+ 3y2 and x3 - y3. Find the perimeter.

Answer 1

Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

Perimeter If Rectangle:- 2 * ( length + breadh)

Given length = 5 x^2 - 3 y^

Breadth = x^2 + 2 x y

Hence Perimeter = 2 ( 5x^2 - 3y^2 + x^2 + 2 x y) = 2 * ( 6x^2 + 2 x y - 3 y^2)

So P = 12 x2 + 4 x y - 6 y2

Answer 2

Answer:

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

Perimeter If Rectangle:- 2 * ( length + breadh)

Given length = 5 x^2 - 3 y^

Breadth = x^2 + 2 x y

Hence Perimeter = 2 ( 5x^2 - 3y^2 + x^2 + 2 x y) = 2 * ( 6x^2 + 2 x y - 3 y^2)

So P = 12 x2 + 4 x y - 6 y2
