Answer:
66.5 cm²
Step-by-step explanation:
A horizontal line at the "knee" on the right will divide the figure into a 4 cm by 2 cm rectangle, and a trapezoid with bases 4 cm and 9 cm, and height 11-2 = 9 cm. Then the total area of the figure is ...
A = LW + 1/2(b1 +b2)h
A = (4 cm)(2 cm) + (1/2)(4 cm +9 cm)(9 cm) = 8 cm² +58.5 cm²
A = 66.5 cm² . . . . area of the figure
If you would like to find the output value for the following function if the input value is 1, you can calculate this using the following steps:
input value ... 1
y = 3x + 1 = 3 * 1 + 1 = 3 + 1 = 4
The correct result would be 4.

a²+b²=c² Pythagorean Theorem
3²+4²=c² simplify
c=√(3²+4²) isolate c
c=5
c*6=answer because you need wire for 6 trees
5*6=answer
answer=30
You will need 30 feet of wire
Divide the numerator and denominator by 3:
15 / 3 = 5
24 / 3 = 8
5/8
