Answer:
A = 216 cm^2
P = 80 cm
Step-by-step explanation:
l = 12
w = 18
As the object is rectangular, the area is height * width and the perimeter is
2(height + width) as there are two of each side.
12 * 18 = 216 U^2 U = unit of measurement, I would presume for a poster you use cm so its 216 cm^2
12 + 18 = 40
40 * 2 = 80 cm
Answer:
255 km

Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).
Answer:
11.25pi units² or 35.3 units² (3 sf)
Step-by-step explanation:
½×r²×theta
½ × 5² × 0.9pi
11.25pi units²
Or, 35.3 units² (3 sf)
The answer is: E
