Answer:
Step-by-step explanation:
Find the area of the shape by creating two shapes. A large rectangle and a very small triangle. The area of the rectangle is 13x12, and the area of the triangle is (1/2)3x4. The area of both shapes together is 6+156=<u>162</u>.
Now you can easily calculate the area of each rug and determine whether it is over half of 162 (because 162 is the area of the entire floor), or under half of 162. If it is under 81, then it does not cover at least half of the floor.
12x6 = 72 no
10x9 =90 yes
13x12 = 156 yes
3x12 = 36 no
8x8 = 64 no
Since it is 6 pounds per dollar, all you would do is divide 18 by 6 and get 3. Thus if you went to go exchange 18 pounds you would get $3 worth of US dollars.
It you have to start from 0cm and count 1 unit every time to get to 2cm
This would be 16
I hope this helped!!!
