What would you tell someone who is trying to find the area of a complex figure?

base times height

I think

I would do this by telling the person to do the formula of the figure and split the pieces into divided

If the shape was a rectangle I would tell them base x high

If it was a triangle I would tell them 1/2 x(ba

I would multiply the base times height, h (b1, b2), or h divided by b times h

I would tell the student to split the figure into regular polygons. Then I would find the area of those shapes using base x height. Then add the area of all the shapes.

I would tell them to decompose the figure to a figure you know to find the area of and then add the areas of the decomposed figures and you have the area

I would tell them to divide the figure into polygons and then find its area by using base x height and add up the area of all shape.

I would tell the student that they should figure out the formula and when they get that follow the steps exactly.

I would tell them to break it into simpler figures

Rectangle: multiply base times height

Triangle: Base plus height divided by 1/2

Trapezoid: 1/2 of height times base two plus base 1

Find the formula and solve it.

Kaylee Gervais

i would split the complex figure

into rectangles, triangles, and parallelograms

and solve each of the polygons area. then i

would add everything together. :)

Madison Chiarito

I would break down the shape into other shapes. Then, I would find the areas of the shapes.

Aneesa Merced

2014-12-16 14:58:02 UTC

i would split the figure into different shapes then

find the area of each figure by multiplying bxh then

adding up all the shapes area together to get the complex

figures area

Giulianna

I would split the figure into regular polygons. so it would make it easier to do the formula.

Tym Sullivan

I would break down the figure in to shapes i know how to work with and then do the formal for each ishape

Lindsay Forauer

I would tell them to break the figure into different rectangles or just different shapes that are easy to find the area of. You then find the area of the individual shapes and add their areas together

Break the figure down

Katie Damato

I would find the area of a complex figure by breaking down the shape. Breaking the shape down makes is easy because then you can just follow the simple steps of finding the area of a parallelogram. Once you take your complicated figure and decompose it you get small, easy to work with shapes. Then if your smaller shapes are parallelograms you can use the method BxH. other methods are....

trapozoid = 1/2h ( b1+b2)

triangle= 1/2 (b x h)

any larger shapes = break down the figure to make smaller shapes. then use on of the methods above

Corrina Vojnich

2014-12-16 15:01:31 UTC

I would use the formulas for the parallelogram- A= B x H,

the trapezoid- A=1/2 (b 1 + b 2) , and finally the

triangle- A= 1/2 h (B x H) . You could also split the shapes into different smaller figures.

Garren Osgood

2014-12-16 15:02:23 UTC

I would tell and explain to them the formula witch for a triangle is 1/2 b times h and for a parralelagram is b times h and for a trapazod is 1/2 bi + b2

Breakdown the shape into shapes you know. Shapes like rectangles squares triangles and paralellogram.

I would tell them to decompse the shape
