Question

a. Find the perimeter of the figure of the following is true:

a=x+7
b=2x+2
c=8x
d=x+10

b. What is the perimeter of the figure in part (a) if x=4? ​

Answer 1

Answer:

a=11, b=10, c=32, and d=14.

Step-by-step explanation:

Answer 2

Answer:

67 units

Step-by-step explanation:

Perimeter  of a shape is the sum of all sides.

Perimeter = a + b + c + d

                = x +7  + 2x + 2 + 8x + x +10

                = x + 2x + 8x + x  +7 + 2 + 10

Combine like terms,

                 = 12x + 19

Now, substitute x = 4 in the above expression,

                  = 12*4 + 19

                  = 48 + 19

                  = 67
