Hi I'm the aunt of a middle school child. He need help with two problems and I don't understand how to show he how to do them. Can you help me.
Can you show me not only the answer but also the steps that you used.
The perimeter of a geometric shape is the length of its boundary. For example the perimeter of a field is the length of fence it takes to surround the field. For your triangle in the first problem the sides are of lengths 4, 0.7 and 5/6. Hence the perimeter is
Likewise for the second problem the perimeter is
= 3X + 1 + X + 4 + 2X + 5
= 6x + 10
