Toski is building a room that is 18 feet long and 14 feet wide. Construct a scale drawing of the shed. Use a scale of inch = 2 f
AURORKA [14]

Answer:

Option A is the answer

Step-by-step explanation:

Toski is building a room having length = 18 feet

Width of the room = 14 feet

Scale has been given as 1 inch = 2 feet

∵ 2 feet = 1 inch

∴ 1 feet = \frac{1}{2} feet

∴ 18 feet length of the room = \frac{18}{2}=9 inches

Similarly 14 feet width of the room = \frac{14}{2}=7 inch

Now we count the small blocks in the given options.

Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.

Option A is the answer.
