Question

What is the perimeter, P, of a rectangle that has a length of x +8 and a width of y - 1?

Answer 1

Answer:

P=2x+2y+14

Step-by-step explanation:

Perimeter (P)of a rectangle = 2( l+b)

where l is the length and b is the width of the rectangle .

Here, l= x+8

and, b= y-1

so, P = 2{(x+8)+(y-1)}

= 2( x+8+y-1)

= 2(x+y+7)

=2x+2y+14
