Masha is making a scale diagram of the front face of an aquarium. the face is shaped like a rectangle. she uses a scale of 1 centimeter to 6 inches to draw the diagram. the actual length of the aquarium face is 5 feet, and its width is 2 feet. the perimeter of the scale drawing of the front face centimeters.

Scale:
1 cm : 6 inches


Length of the aquarium:

5 feet = 5 x 12 = 60 inches
60 ÷ 6 = 10 
The length will be 10 cm on the scale drawing.


Width of the aquarium:

2 feet = 2 x 12 = 24 inches
24 ÷ 6 = 4 

The width will be 4 cm on the scale drawing.


Find Perimeter:

Perimeter = 2 (length + width)
Perimeter = 2( 10 + 4 )
Perimeter = 28 cm


  The perimeter of the scale drawing of the front face is 28 cm.

31 is prime. and it’s prime factorization is just 31.
