Either 200.855 or 210,000,00 depending on if the e represents 10
6= - 5/4 (-4) +b
6=-5+b
11=b
y=-5/4+11
Answer:
496 cm²
Step-by-step explanation:
Area of polygon :
A = 1/2(p * a)
P = perimeter
a = apothem
Perimeter = 5s (pentagon)
s = side length = 18
P = 5 * 18 = 80 cm
a = 12.4
A = 1/2(80 * 12.4)
A = 1/2(992)
A = 496 cm²
