Answer:

C. 4yd * 3ft/yd * 12in/1ft * 2.54cm/1.in = 365.76cm

Step-by-step explanation:

First you change 4 yards into feet (By multiplying the 4 yard by 3 ft/1yd)

then you convert 12 feet into inches (By multiplying the 12 feet by 12in/1ft)

after you convert 144 inches to cm (By multiplying the 144 in by 2.54 cm/1in)

you’ll have the value in cm. Which is 365.76.

Answer:

Perimeter of the final star = 40 cm²

Step-by-step Explanation:

The perimeter of the six-pointed star is the sum of the sides of the 6 equilateral triangles that form a boundary around the star.

1 triangular tiles gas a perimeter of 10cm.

Only 2 out of the 3 equal sides of each of the 6 equilateral triangles form the boundary of the final star.

Therefore, perimeter of the final star = ⅔ of the total perimeter of 6 triangular tiles

= ⅔ of (10*6)

= ⅔*60

= 2*20

Perimeter of the final star = 40 cm²
