A game room has a floor that is 400 feet by 90 feet. A scale drawing of the floor on grid paper uses a scale of 1 unit:5 feet. What are the dimensions of the scale drawing? Enter your answer as length by width.

Respuesta :

first 1/5 is equivalent to 20% so to get 20% of both of them multiply by .2. so 400×.2=80 and 90×.2=18

Answer:

80 units by 18 units

Step-by-step explanation:

Find the number of feet represented by 1 unit in the drawing.

1 unit ÷ 1

5 feet ÷ 1

 =  

1 unit

5 feet

1 unit in this model is about 5 feet in the actual room.

Find the width of the scale model represented by 90 feet in the actual room.

1 unit × 18

5 ft × 18

 =  

18 units

90 ft

The width of the scale model represented by 90 feet in the actual room is 18 units.

Find the length of the scale model represented by 400 feet in the actual room.

1 unit × 80

5 ft × 80

 =  

80 units

400 ft

The length of the scale model is 80 units.

The scale model is 80 units by 18 units.
