Answer:
13.5 inches
Step-by-step explanation:
Perimeter of the paper square = 18inches
Perimeter of a square = 4s
4s = 18 inches
s = 18/4 = 4.5 inches
Therefore, each side of the square = 4.5 inches.
When the square is cut into 2 rectangles,
The perimeter of one of the rectangles is 10 inches.
Perimeter of the second rectangle = 2L + 2W
Let the length of the rectangle (L) = one side of the square = 4.5 inches
Width of the Rectangle = Length of the square/2 = 4.5 inches/ 2 = 2.25
Perimeter of the second rectangle = 2(4.5) + 2(2.25)
= 9 + 4.5
= 13.5 inches

Answer:
just divide 60 by 4 then mutiply by six
Step-by-step explanation:
There are 20 blocks needed for tower A, and 43.75 blocks needed for tower B
From the tape diagrams, we have the following ratio
Prism : Pyramid = 4 : 1
From the table, we have:
Tower A = 16 prisms
So, the ratio becomes
16 : Pyramid = 4 : 1
Multiply the ratio on the right-side by 4
16 : Pyramid = 16 : 4
By comparison, we have:
Pyramid = 4
This means that, 4 pyramid blocks are needed for tower A
So, the total number of blocks needed is:
Total = Pyramid + Prism
This gives
Total = 4 + 16
Evaluate the sum
Total = 20
Hence, there are 20 blocks needed for tower A
For table B, we have:
Tower A = 35 prisms
So, the ratio becomes
35 : Pyramid = 4 : 1
Express as fractions

Multiply through by 35
Pyramid = 8.75
This means that, 8.75 pyramid blocks are needed for tower B
So, the total number of blocks needed is:
Total = 8.75 + 35
Evaluate the sum
Total = 43.75
Hence, there are 43.75 blocks needed for tower B
