Garden G

The rectangular trapezoidal garden has a base length of 81m, 76m, and a vertical arm of 12m. Calculate how many m2 of area will remain for planting greenery, if 1/3 of the area is built. Calculate the consumption of mesh for land fencing.

Correct result:

S =  1256 m2
o =  106 m

Solution:

a=81 m c=76 m d=12 m  S1=a+c2 d=81+762 12=942 m2  S=S1+13 S1=942+13 942=1256 m2
c=d2+(ac)2=122+(8113)2=13 m  o=a+b+c+d=81+b+13+12=106 m
