Question

What is the value of x if a rectangle has a perimeter of 50, a length of x + 5, and width of 11?

Answer 1

Answer: 9

Explanation:

2[(x+5)+11]=50

2[x+16]=50

2x+32=50

2x=18

x=9 There you go! So this is your answer. Your missing 'x' equals 9.

Answer 2

x = 9

Explanation:

Perimeter = 2 * width + 2 * length

= 2*11 + 2(x + 5) = 50

2x + 10 + 22 = 50

2x = 50 - 10 - 22

2x = 18

x = 9
