Answer:
The area of the composite figure is 392.12
.
Step-by-step explanation:
The area of the composite figure = area of trapezoid + area of rectangle
Area of trapezium =
( a +b)h
Where: a is the length of the first base, b the length of the second base and h is the height of the trapzium.
Applying Pythagoras theorem, the height, h, is;
h = 
= 
h = 2
Area of trapezium =
( a +b)h
=
(13 + 12) × 2
= 156
= 382.12
Area of trapezium is 382.12
Area of rectangle = length × width
= 5 × 2
= 10 
Area of rectangle = 10 
Therefore,
area of the composite figure = 382.12 + 10
= 392.12

Answer:
Rounding x = 5.52
Step-by-step explanation:
2.1x - 3.6 = 8
Add 3.6 to each side
2.1x - 3.6+3.6 = 8+3.6
2.1x = 11.6
Divide each side by 2.1
2.1x/2.1 = 11.6/2.1
x =5.523809524
Rounding x = 5.52
