1. UNDERSTAND
A. What is asked?
- The area of the roller rink floor
- The cost of hardwood flooring
B. What are the given facts
- 80 ft – lenght, 40 ft – width, 20 ft – radius and P200 per square foot
2. PLAN
Lets analyze and identify the figures, The figures that we can easily identify are the rectangle and the two semi-circle. Find the area of each figure
3. SOLVE :
Area of rectangle
A = L × W
Area of the Circle
[tex]A = \pi r^{2} [/tex]
[tex]A = \pi(20ft)^{2} [/tex]
[tex]A = 3.14 \times 400 {ft}^{2} = 1 \: 256 {ft}^{2} [/tex]
[tex]area {\tiny{total}} \: = area{ \tiny{rectangle}} \: + area{ \tiny{circle}}[/tex]
[tex]area {\tiny{total}} = 3200 + 1256 \\ = 4456 {ft}^{2} [/tex]
If hardwood flooring costs P200 per square foot, then:
4 456 ft² × P200 = P891 200
4. CHECK : P891 200 ÷ P200 = 4 456
