Assuming the triangle is an equilateral triangle, each side is equal to 42/3 = 14 millimetres long. Increasing the sides by 50 percent makes each side 14 x (1 + 50/100) = 14 x 1.5 = 21 millimetres. Therefore, the perimeter of this new triangle will be 21 x 3 = 63 millimetres.
30+4+2=36
There's no question there. Something is missing. But your math book probably explains how to solve this anyway.
"...increased by four percent" is a fragment because it lacks a subject. WHAT increased by four percent?

Perimeter of a square = 4 sides Answer: 1 side = 25% of the Perimeter
You need to define your terms better. Percentage of what? Maybe give us the context and we can rephrase and answer your question. If you mean percentage of a liter, then simply multiply the percent by 10.
The answer is 22,22 %.
66 increased by 88 percent = 124.1
95 increased by 90 percent = 180.5
22,500 increased by 4 percent = 23,400
3000 increased by 6 percent = 3,180
2.81 increased by 5 percent = 2.9505
