Answer:
Step-by-step explanation:
8p+3f=10.39
5p+4f=10.51
subtract
3p-f=-0.12
f=3p+0.12
8p+3(3p+0.12)=10.39
17p=10.39-0.36
17p=10.03
p=10.03/17=0.59
f=3×0.59+0.12=1.77+0.12=1.89 $
or 40 p+15f-40p-32f=51.95-84.08
-17f=-32.13
f=1.89 $
The square root of 700 is about 26.45, so it lies between 26 and 27
Area of trapezoid = Average length of parallel lines x height
3+22=25
25/2= 12.5
12.5x6=75cm^2
