Answer:
x < 1
Step-by-step explanation:
x+9<10
Subtract 9 from each side
x+9-9<10-9
x < 1
There are 1 right triangle, 1 rectangle and 1 trapezoid
- Solve for right triangle
1/2 x 5 x 8 = 20 cm
- Solve for rectangle
12 x 8 = 96 cm
- Solve for trapezoid
1/2 x 9 ( 5 + 10 ) = 67.5 cm
- The area of this is
20 + 96 + 67.5 = 183.5 cm
hope it useful for you :)
