The perimeter of a triangle is the sum of its sides​

​Perimeter = 21/2 inches + 31/4 inches + 5 inches =

​Perimeter = 21*2/2*2 inches + 31/4 inches + 5*4/4 inches =

Perimeter = 42/4 inches + 31/4 inches + 20/4 inches =​

Perimeter = (42 inches + 31 inches + 20 inches)/4 = 93/4 inches

Answer : 93/4 inches​

Hope this helps!​​​​​
