square and triangle
You have to cut the trapezoid into three shapes. The three shapes will be two triangles and one rectangle or square. You have to find the area of these three shapes and then add all of the three areas up to find the area of the trapezoid.
You are not finding the area you are finding the volume. The answers is 1232 cm3
Area of a trapezoid = 0.5*(sum of parallel sides)*height
The answer depends on the relative sizes of the two shapes.
The formula for finding the area of a trapezoid is:A = (1/2) (b1 + b2 ) h
Area = 1/2*(sum of the two bases)*height
A=m*h m=(a+b)/2
Area = 1/2*(sum of parallel sides)*perpendicular height
By finding the total area, you can see if all of the areas of your shapes combined match the total area of the rectangle. It's a safe-check.
The formula for the area of the shape really depends on the shape. Some of the following are the areas of certain shapes: Rectangle area = lw (length x width) Parallelogram area = bh (base x height) Triangle area = 1/2 bh Trapezoid area = [(b1 + b2)/2] h There are other shapes as well that require different formulas for finding their area.
Area measured in square units = 1/2*(sum of the parallel sides)*height
Area = 1/2*(sum of parallel sides)*height and measured in square units
