Question

Thats all of my points plz help me

Reuben is making a replica of the US flag for his school project.
He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters.
The perimeter of the scale drawing is (a7.25, b 11.875, c 14.5 d 47.5)centimeters
The perimeter of the actual flag is(a 14.5 b 29 c 47.5 d 95

Answer 1

Explanation:

Perimeter of scale drawing

= 2 * (Length + Width)

= 2 * (2.5cm + 4.75cm)

= 2 * 7.25cm

= 14.5cm. (C)

Scale length to Actual length = 0.5cm : 1 in

Hence,

Perimeter of actual drawing

=> (1/0.5) * Perimeter of scale drawing

=> (1/0.5) * 14.5cm

=> 29 in. (B)

Answer 2

Given: U.S Flag - rectangle in shape

scale of 0.5 cm = 1 in

length of the scale 2.5 cm

width of the scale 4.75 cm

perimeter of the scale = 2(L+W) = 2(2.5+4.75) =

2(7.25) = 14.5cm

perimeter of the actual flag is:

14.5cm * 1in/0.5cm = 29 inches

hope it helps!
