If the length of the sides of this triangle are in the extended ration: 3: 10:12; then we can express the length of its sides as: 3x ,10x and 12x.
The length of the longest side will be: 12x
Perimeter of a rectangle is the sum of all sides.
Therefore
We can suggest the following equation:
3x+10x+12x=400
25x=400
x=400/25
x=16
Therefore; the length of the sides would be:
3x=3(16)=48
10x=10(16)=160
12x=12(16)=192
Answer: the length of the longest side would be 192 cm.

Answer:
10 km / hr
Step-by-step explanation:
Speed of boat = 15 km /hr
Speed of stream = 5km /hr .
Since both are acting opposite to each other . The the resultant speed with which it travels = 15 - 5 = 10 km/hr
Answer:
40%
Step-by-step explanation:
Total students = 30
No. of girls. = 12
Girls % = ?
