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

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

Explanation:

Answer 2

67 units

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
