Find the perimeter of a triangle with sides 2ft 4in, 3ft, and 4ft 6in.
2 ft and 4 inches = 28 inches
3 ft = 36 inches
4 ft and 6 inches = 54 inches
Per = 28+36+54 = 118 inches
= 9 ft and 10 inches
To find the perimeter of a triangle, you need to add the lengths of all three sides.
Let's calculate the perimeter step by step:
1. Convert all the measurements to the same unit. In this case, let's convert everything to inches because it is a smaller unit than feet.
2ft equals 2 * 12 = 24 inches.
4in remains as it is.
3ft equals 3 * 12 = 36 inches.
4ft 6in equals 4 * 12 + 6 = 48 + 6 = 54 inches.
2. Now that all the sides are in inches, we can add them up:
Perimeter = 24 inches + 4 inches + 36 inches + 54 inches
3. Add up the numbers:
Perimeter = 118 inches.
Therefore, the perimeter of the triangle is 118 inches.
