Portion 1=15.33, Portion 2=8.17 , Portion 3 = 10.33 and Portion 4=9.17
Step-by-step explanation:
You can approximate the areas of the trapezoidal portions as follows;
Area=1/2(a+b)h where
a=length of shorter side of the trapezoid portion
b=length of longer side of the trapezoidal portion
h=height of the trapezoidal portion
In Portion 1
a=5, b=11, h=2
Area=1/2(5+11)2 = 16 square units
In Portion 2
a=3, b=5,h=2
Area= 1/2(3+5)2 =8 square units
In Portion 3
a=3.5, b=7, h=2
Area=1/2(3.5+7)2 =10.5 square units
In Portion 4
a=7, b=11, h=1
Area= 1/2 (7+11)1 =18/2= 9 square units
From the values given, correct location for the areas in 2 decimal places will be;
Portion 1=15.33, Portion 2=8.17 , Portion 3 = 10.33 and Portion 4=9.17
