Answer:
42.5 units²
Step-by-step explanation:
Total height of rectangle = 3.5 + 2 = 5.5 units
Total area (without triangles removed) = 5.5 x 9.0 = 49.5 units²
The measurements and area of the triangles removed are equal to those on the diagram, so calculate the area of the triangles and subtract them from the total area.
Left: (0.5)(2)(2) = 2 units²
Right: (0.5)(5)(2) = 5 units²
Area: 49.5 - 2 - 5 = 42.5 units²
You have to know how to enter this into your calculator. Step by step: hit the stat button and then edit. Enter your x values one at a time in the first column, hitting enter after each value. When finished with x's, arrow over to the second column and enter each y value in, one at a time, hitting enter after each value. When you're done, hit stat again, tab over to calc and hit enter. You will then arrow down to LinReg(ax+b). Hit enter. If you have a TI 83, then the equation should just generate automatically. If you have a TI84 family, you need to arrow down to "calculate" and then hit enter. Your equation will then generate. It is the last choice above, y = 1/2x + 4. Learn how to use your calculator; it can do SO many cool things for you!!!
Answer:
For a square or rectangular room you will need the length and width
Then you multiply I.e length x width gives Area
