Answers
Given : sailboats
Triangle shape
To Find : area
Solution:
Area of Triangle = (1/2) * b * h
Area of Left one
= (1/2) 10.9 * 19.5 + (1/2) (21.9) * 8.6
= 106.275 + 94.17
= 200.445
= 200.4 m²
Right side one
Smaller area = (1/2) * 3 * 8.9 = 13.35 = 13.4 m²
Bigger one
= (1/2) *9.6 * 16.8 + (1/2) * 25 * 12.4
= 80.64 + 155
= 235.64
= 235.6 m²

Answer:
235.64
Step-by-step explanation:
ABC AC =22+20=42
bd=height=22.3
ABC=1/2 multiplied 42 multiplied 22.3=936.6/2
ACE, EF=height=16.8
AC=base=22+22=42m
ACE=1/2 multiplied 42 multiplied 16.8=705.6/2=352.8
