Item 9 Write an equation that you can use to find the value of x. Perimeter of triangle: 16 in.

16 = 3x

Step-by-step explanation

Find the diagram attached.

Perimeter = sum of all its sides

Sum of all its sides= x+x+x

Sum of all its sides = 3x

Given perimeter = 16in

Equating both;

3x = 16

x = 16/3

x = 5.33in

Hence the value of x is 5.33 and the required equation is 16 =3x

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
