Question

Explain how you solve the question

Answer 1

Perimeter: 24 yards

Cost: $144

Explanation:

There are 3 feet in a yard. In the picture, it's given that the length of a side in the hexagon is 12 feet.

12 / 3 = 4 yards

Each side in the hexagon is equal, so the length of every side is 4 yards.

There are 6 sides in a hexagon, meaning the perimeter is 4 * 6 = 24 yards.

The cost per yard is $6.

$6 * 24 yards = $144 to edge the garden with brick.

Answer 2

Perimeter = 72 feet (24 yards) Cost = $144

Explanation:

A hexagon has 6 sides, and each side is 12 feet long

6 x 12 = 72

So she needs 72 feet of brick

But the brick is sold in yards, so convert feet to yards

1 yard = 3 feet

72 / 3 = 24

So the perimeter of the garden is 72 feet or 24 yards

If the brick costs $6 per yard then multiply 24 x 6 to find the cost

24 x 6 = 144

So the total cost is $144
