Answer:
[tex]\huge\boxed{c)\ A=104\ m^2}\\\boxed{d)\ A=200\ cm^2}[/tex]
Step-by-step explanation:
They are the trapezoids. The formula of an area of trapezoid is:
[tex]A=\dfrac{b_1+b_2}{2}\cdot h[/tex]
[tex]b_1;\ b_2[/tex] - parallel bases
[tex]h[/tex] - height
c)
[tex]b_1=16m\\b_2=10m\\h=8m[/tex]
substitute:
[tex]A=\dfrac{16+10}{2}\cdot8=\dfrac{26}{2}\cdot8=13\cdot8=104\ (m^2)[/tex]
d)
[tex]b_1=35cm\\b_2=15cm\\h=8cm[/tex]
substitute
[tex]A=\dfrac{35+15}{2}\cdot8=\dfrac{50}{2}\cdot8=25\cdot8=200\ (cm^2)[/tex]
