Answer:
204.2 cm
Step-by-step explanation:
equilateral means all sides are of equal length.
the perimeter of such a triangle is simply 3 times one of these sides.
so,
612.6 = 3×0.2×(10x + 90) = 0.6×(10x+90) = 6x + 54
6x = 558.6
x = 93.1
so, a single side is
0.2×(10×93.1 +90) = 0.2×(931 + 90) = 0.2×1021 = 204.2 cm
to check
3×204.2 = 612.6 = the original perimeter.
so, correct.
In order to solve this problem, you need to find out how 3 of something is 30
In this case, you multiply 10.
Sean= 3×10=30
Ryan= 4×10=40
Justin= 5×10= 50
30+40+50= 120
The answer is $120
