Perimeter is adding all the sides together. If the height is 16, 16×2 for the two sides would be 32. And 58-32=26. 26 is the other two sides added together so 26÷2=13 13 is the answer
A) <span>3x + </span><span>2.5y= 27 B) 5x – 2.5y = 5 </span>Adding A and B we get 8x = 32 x = 4 A) 3*4 + <span>2.5y= 27 </span>A) 12 + <span>2.5y= 27 </span>A) <span>2.5y= 15 y = 6
