Answer:
Answer:
a = 22 cm
b = 45 cm
c = 43 cm
Explanation:
Perimeter of a Triangle = a + b + c
110 cm = a + b + c
A triangle has three sides.
a = First side
b = second side
c = Third side
The second side is more than double the first side
= b = 2a + 1
The third side is three less than the first side.
= c = 2a + 1 - 2
The perimeter is 110 cm. How long are the sides?
a + 2a + 1 + 2a -1 = 110
5a = 110
a = 110/5
a = 22 cm
2a +1 = b
2(22) + 1 = 45
b = 45 cm
For c
2a - 1 = c
2(22) - 1 = c
c = 44 - 1
c = 43 cm
