Question

A rectangle has a length (x2 + 4y) unit and a breadth of (-2x + y3) unit. Find its perimeter.​

Answer 1

Answer:

$length \: = x {}^{2} + 4y$

$breadth \: = - 2x + y {}^{3}$

$perimeter \: of \: rectangle=2(l+b)$

$= 2(x {}^{2} + 4y + ( - 2x + y {}^{3})$

$= 2(x {}^{2} + 4y - 2x + y {}^{3} )$

$= 2x {}^{2} + 8y - 4x + 2y {}^{3}$

$= 2y {}^{3} + 2x {}^{2} + 8y - 4x$
