Which are ways to decompose the composite figure into simpler shapes that you have area formulas for? Check all that apply.

1) separate the figure into simpler shapes whose area can be found. Then add the areas together.

2. Add smaller shapes to the composite figure that equal a larger shape to save time. Here it is useful as it also helps you find quicker measurements for opposite lines. So always look for opposite lines when considering adding a viable shape. Such shape needs to have the same equal measurement as another that cna be dotted lines and found quickly too.

3. Remember formulas.

Area Triangle  = B x H /2

Area Parallelogram = B x H

Area Square rectangle =  L x W  

Area Semi Circle = pi * r^2/2

Area Sector Circle  =  θ × π 360 × r2 (when θ is in degrees)

Area of Segment = ( θ × π 360 − sin(θ)2 ) × r2 (when θ is in degrees)

Length of a circle = L = θ × π180 × r (when θ is in degrees)

The Area of a Segment is the area of a sector minus the triangular piece usually highlighted and so you add this to equal 360 degree.

10 * 563.67 = 5636.7

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
