1. UNDERSTAND
A. What is asked?
B. What are the given facts
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
