First, we know the area of a square is side length side length = Area. For this square, the area would be:
18*18=A
324 = A
Now that we know the area that is being referened, we can look at the formula for the area of a rectangle, which is width * length = Area. We know the length and we know the area, so we can fill in these known values and solve for the unknown width.
w*l = A
w*6=324
w=324/6
w=54
So our rectangle has the width of 54 and the length of 6. Lastly, the formula for perimeter is 2w + 2l = P. We can again fill in our knowns and solve for the unknown.
2(54) + 2(6) = P
108 + 12 = P
120 = P
The perimeter of the rectangle is 120 cm.
Answer: 10 ft = 10(12) = 120 inches. Area = length x width. Area = 96(120) = 11520 sq. in. An 8 inch square = 8 x 8 = 64 sq. in. 11520 divided by 64 = 180 tiles.

Step-by-step explanation:
For the question with colored rectangles, it asks to find the area.
The area can be found by multiplying the dimensions of the rectangle.
Blue rectangle :
- A = 10 ft. x 6 ft.
- A = <u>60 ft²</u>
<u></u>
Green rectangle :
- A = 12 cm. x 8 cm.
- A = <u>96 cm²</u>
<u></u>
Question 13 :
- Here, we are given 2 rows and 7 columns
- Take them as the dimensions
- Hence, area = 2 x 7 = <u>14 square units</u>
(7a-b+3)-(-2a-8b+8)
Apply plus/minus rule.
-(-a)= a and -(a)=-a
we get
(7a-b+3)-(-2a-8b+8)= 7a-b+3+2a+8b-8
Add like terms
=9a+7b-5
Answer: 9a + 7b - 5
