Question

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

Answer 1

Step-by-step explanation:

how do we find area? Length x width, right?

 

Let's break up each part.

 

3x3y2 = 3(x)(x)(x)(y)(y)

5x2y3 = 5(x)(x)(y)(y)(y)

 

Combining everything we have, 3(5)(x)(x)(x)(x)(x)(y)(y)(y)(y)(y). That's 15x5y5.

 

We multiply the coeffiecients and add exponents with the same base.  

 

Hope this helps!
