Answer:
146 ft²
21.6 tiles
1.8 boxes
Step-by-step explanation:
Please find attached an image of the family room used in answering this question
the family room has the following shapes : 2 triangles and one rectangle
the area of the family room can be determined by calculating the area of each of the shape and adding the 3 areas together
area of a rectangle = length x breadth
16 x 7 = 112 ft²
Area of a triangle = 1/2 x base x height
Area of the smaller triangle = (1/2) x 4 x 3 = 6 ft²
Area of the bigger triangle = (1/2) x 8 x 7 = 28 ft²
Sum of the areas = 112 + 6 + 28 = 146 ft²
b.
1. First convert the area of the room to inches
1 ft = 12 in
146 x 12 = 1752 in²
2. the next step is to determine the area of the tile
area of a square = length²
9² = 81 in²
3. Divide the area of the room by the area of the tile
1752 / 81 = 21.6 tiles
c. total number of boxes that would be bought = 21.6 /12 = 1.8 boxes
Answer:
Rhada can make 48 ornaments if she uses all of the clay.
Step-by-step explanation:
The complete question is:
Rhada has a 6-pound bag of day . Her craft project requires 6 ounces of clay for each batch of 3 ornaments. If she uses all of the clay, how many ornaments can Rhada make?
Solution:
The amount of clay Rhada has, <em>X</em> = 6-pound.
Convert the weight of clay bag into ounces as follows:
1 pound = 16 ounces
6 pound = 16 × 6
= 96 ounces.
So, Rhada has 96 ounces of clay.
It is provided that her craft project requires 6 ounces of clay for each batch of ornaments.
Compute the number of batches that can be made by 96 ounces of clay as follows:
Number of batches = Total weight of clay ÷ Amount required for each batch
Thus, Rhada can make 16 batches of ornaments.
Now, it is also provided that each batch has 3 ornaments.
Compute the number of ornaments in 16 batches as follows:
Number of ornaments = Number of batches × No. of ornament in 1 batch
Thus, Rhada can make 48 ornaments if she uses all of the clay.
