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

Answer:
True
Step-by-step explanation:
Answer:
B. Add 115+500 then subtract 3
C. Add 112+500
Step-by-step explanation:
Any strategy that gives a sum of 612 will work. Strategy A gives a sum of 602, so is not useful.
The appropriate choices are B and C.
B: 115 +497 = 115 +(500 -3) = (115 +500) -3
C: 115 +497 = 115 +497 -3 +3 = (115 -3) +(497 +3) = 112 +500
