Answer:
Step-by-step explanation:
Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2
First parallelogram has h=4cm (from first triangle) and a=5.7cm
P2=a*h=22.8cm^2
Big triangle has h=4 and a=5.7+4=9.7
P3=a*h/2=9.7*4/2=19.4
And 4th triangle has the same are lik the first one, P4=8.
P=8+22.8+19.4+8=58.2cm^2
399.6 square meters
7•8/2=28
28•3=84
8•6.9/2=27.6
(12•8)•3=288
84+27.6+288=399.6
