Question

The width of a rectangle is 2 cm less than its length. The perimeter is 52 cm. The length is:

14 cm.
12 cm.
9 cm.
None of these choices are correct.

Answer 1

Answer: 14 cm

Explanation:

Rectangle:

• Length = x
• Width = x - 2

x + x + (x - 2) + (x - 2) = 52

2x + 2(x - 2) = 52

2x + 2x - 4 = 52

4x = 52 + 4

4x = 56

x = 14
