Question

Molly is making a quilt for her mother. The quilt will have several designs. One of the designs is shown below. What is the total perimeter of this design, in inches? A. B. C. D.

Answer 1

Answer: A. 12 + 12√12

Explanation:

The perimeter of a triangle is acquired by adding up all the sides of the triangle.

In this case therefore the perimeter is;

= 2√2 + 2√2 + 4

= 4√4 + 4

There are 3 triangles so the total perimeter is;

= 3 * (4√4 + 4)

= 12√12 + 12

= 12 + 12√12
