A scale of a room in a blueprint is 3 in.:5 ft. A wall in the same blueprint is 18 in. How long is the actual wall? 30 feet
A window in the room has an actual width of 2.5 feet. Find the width of the window in the blueprint. 1[tex]\frac{1}{2}[/tex]
Answer:
Length = 30cm Width= 20cm area = 600m
Step-by-step explanation:
Find the number of meters represented by 1 centimeter in the drawing.
2 cm ÷ 2
5 m ÷ 2
=
1 cm
5
2
m
1 centimeter in this model is
5
2
meters in the actual room.
Find the width of the actual room labeled 8 centimeters in the drawing.
1 cm × 8
5
2
m × 8
=
8 cm
20 m
The width of the actual room labeled 8 cm is 20 m.
Find the length of the actual room labeled 12 centimeters in the drawing.
1 cm × 12
5
2
m × 12
=
12 cm
30 m
The length of the actual room is 30 m.
Since the area is length times width, the area of the actual room is 30 m × 20 m = 600 m2.
