Answer:
50cm
Step-by-step explanation:
If the sides are consecutive odd integers,
Let the smallest side=y
The other sides are y+2 and y+4
The perimeter=144cm
y+y+2+y+4=144
3y+6=144
3y=144-6
3y=138
y=138/3=46cm
Therefore, the largest side of the triangle:
y+4=46+4=50cm
Therefore, the largest side of the triangle is 50cm
Take that certain number we are looking for as 'n'
38% ⇒ 0.38
0.38n = 152
Divide by 0.38
0.38n = 152
/0.38 /0.38
n = 400
So 38% of 400 is 152.
