Answer:
22.5 cm
Step-by-step explanation:
An equilateral triangle has 3 equal sides
perimeter is the sum of all 3 sides, hence
perimeter = 3 × 7.5 = 22.5 cm
5/2=2 1/2 + 2/5 = 2.9 = 2 9/10
34% . <span>Since going from 75% to 82% is simply the right portion of that middle, the answer is half of 68%, or 34%.</span>
