Question

The length of a rectangle is (x+22. The width of the rectangle is (x^2+1). Which expression represents the perimeter of the rectangle?

Answer 1

Hi

Perimeter is the sum of all sides of the rectangle.

It have 2 width

2 length ( x²+1)

So : one width is (x+22) so 2 is 2 * (x+22)

length is (x²+1) so 2 is 2* ( x²+1)

So perimeter is : 2 (x+22) + 2 (x²+1)

2 ( x+22 +x²+1)

2 ( x²+x+23)

perimeter is : 2x² +2x+ 46
