Answer:
x=27.5
FG=72.5
GH=60
HF=47.5
Step-by-step explanation:
Sum of angles in a triangle=180
Therefore, FG+GH+HF=180
Substituting the values we have,
(3x - 10) + (2x+5) +(x+20) = 180
Collecting like terms
3x+2x+x = 180 +10 - 5 - 20
6x = 165
X= 27.5
FG = (3x - 10) = 3(27.5) - 10
FG= 72.5
GH= (2x+5) = 2(27.5)+5
GH=60
HF= x+20 =27.5+20
HF=47.5

Answer:
141
Step-by-step explanation:
Area of a trapezium = 
(a + b)
h = height
a and b = upper and and lower lengths
Area of a trapezium = 
(10 + 16)
= × 26
= 117
Area of a triangle = 
× base × height
= × 6 × 8
= × 48
= 24
Total area = Sum of the areas of both the shapes
= 117 + 24
= 141
