Question

What is the perimeter of this rectangle?

Answer 1

24 units

From observation:

length: 7 units

width: 5 units

solve for perimeter:

• 2 ( length + width )

• 2 ( 7 + 5 )

• 2 ( 12 )

• 24 units

Answer 2

24 units

Explanation:

From inspection of the diagram:

• width = 5 units
• length = 7 units

perimeter of a rectangle = 2 x width + 2 x length

⇒ perimeter = 2 x 5 + 2 x 7 = 10 + 14 = 24 units
