The area of a parallelogram follows the following formula
[tex]A=bh[/tex]
Where b = 9cm and h = 7cm.
[tex]A=9\operatorname{cm}\times7\operatorname{cm}=63(cm)^2[/tex]
The area of the parallelogram is 63 square centimeters.
The area of a triangle is
[tex]A=\frac{bh}{2}[/tex]
Where b = 10cm and h = 6.8 cm.
[tex]A=\frac{10\operatorname{cm}\times6.8\operatorname{cm}}{2}=34(cm)^2_{}[/tex]
The area of the triangle is 34 square centimeters.
The area of a trapezoid is
[tex]A=\frac{(B+b)h}{2}[/tex]
Where B = 15cm, b = 13cm, and h = 6cm.
[tex]A=\frac{(15\operatorname{cm}+13\operatorname{cm})6\operatorname{cm}}{2}=84(cm)^2[/tex]
The area of the trapezoid is 84 square centimeters.
