![]() ![]() Write ft² after the 184 Now you`re done with the math.Ģ8. Take a pencil and write down “area for paint = 184”Ģ7. Re-write the set-up: change all of the words you can for actual given numbers:Ģ6. ![]() Write down the procedure for the problem:Īrea of feature wall – area of fireplace – area of TV inset = area for paintĢ4. Now recognize that the areas of the fireplace and TV inset are to be subtracted from the total area of the feature wall.Ģ3. Take a pencil and write down “TV inset area = 12”Ģ1. Re-write the formula: change all of the words you can for actual given numbers:Ģ0. The area of the TV inset needs to be calculated.ġ8. The area of it is not given, only its size. Look at the given measurements for the TV inset. The unit for area is ft².ĭone with the fireplace, now the TV inset.ġ6. Take a pencil and write down “fireplace area = 24”ġ5. ![]() Re-write the formula: change all of the words you can for actual given numbers:ġ4. The area of the fireplace needs to be calculated.ġ2. Look at the given measurements for the fireplace. Yes, we`ve got the area of the WHOLE wall. Take a pencil and write down “feature wall area = 220”ĩ. Re-write the formula: change all of the words you can for actual given numbers: Re-write the formula: change all of the letters into words, according to their meaning:Ħ. The idea is to visualize the problem before any math is done.ĥ. Identify that the area of a rectangle is to be calculated.ģ. The area (A) of a trapezoid with a long base B = 6 cm, a short base b = 4 cm and a height h = 3 cm isĪdditional Information: Another Way To Get The AnswerĬalculate the area of wall to be painted, height = 22 feet, width = 10 feet, less a fireplace with a height of 4 feet, width = 6 feet, and a TV inset height = 3 feet, width = 4 feet.ġ. The area (A) of a parallelogram with a base B = 5 cm, and a height h = 4 cm isĪ trapezoid has a shorter base (b) and a longer base (B) and a height (h) that is measured inside or outside the shape perpendicularly to the base. Base (B) is measured along its long side, height (h) is measured inside or outside the shape perpendicularly to the base. You can find formulas below that condense the area calculations into 1 short formula.Ī parallelogram is a skewed rectangle. ![]() Sometimes the above lengthy approach can be shortened. See Episodes 19 & 21 on area of rectangles and triangles. Their areas can also be calculated by adding up the areas of those triangles and rectangles. Parallelograms, Trapezoids, Hexagons, Octagons and other geometric shapes can be broken up into triangles and rectangles. Watch the video to see calculating the area of a feature wall. Area can be calculated by breaking up a composite shape into simple shapes and adding up their areas. ![]()
