Question

The perimeter of a rectangle is 50 inches. Its width measures 11 inches. What is its length? Let x= length of the rectangle. A.) 2x - 11 = 50

B.) 2x + 11 = 50
C.) x + 11 = 50
D.) 2x + 22 = 50

Answer 1

Answer: D.) 2x + 22 = 50

Explanation:

P=2(l+w)

2x+22=50 is correct because

2 times x is 2 times the unknown length

11 times 2 is 22 so, you add that to the 2x

50 is the perimeter
