As many points as I can give and a brainliest and a new friend, please help me!!!
Use the formula [tex]A=\frac{1}{2}bh[/tex] for the area of a triangle to develop formulas for the following shapes. Use diagrams to support your argument.
a. a parallelogram (the area of a parallelogram is [tex]A=bh[/tex], use the triangle formula to explain where this comes from)
b. a trapezoid (the area of a trapezoid is [tex]A=\frac{1}{2}h(b_{1}+b_{2})[/tex], use the triangle formula to explain where this comes from)
