Garden G

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

Correct answer:

S =  1256 m2
o =  106 m

Step-by-step explanation:

a=81 m c=76 m d=12 m  S1=2a+c d=281+76 12=942 m2  S=S1+31 S1=942+31 942=1256 m2
c=d2+(ac)2=122+(8113)2=13 m  o=a+b+c+d=81+b+13+12=106 m
