3x - 6 = 7x + 18
(Move terms)
3x - 7x = 18 + 6
(Collect the terms)
(Calculate the sum)
-4x = 24
(Divide both sides by -4)
x = -6
Answer: 239 m^2
Step-by-step explanation:
Find the area for parts of the shape first.
12 x 5 = 60 x 2 (2 same looking parts) = 120
17 x 7 = 119
Add together values:
120 + 119 = 239 m^2
