Answer 1

(12) The perimeter of the four shaped figure is 12x - 10

(13) The perimeter of the rectangle is 18x + 10

(14) The perimeter of the hexagon is 24x

Explanation:

(12) The perimeter of the four shaped figure is calculated as;

P = (x ) + (3x + 2) + (6x - 17) + (2x + 5)

Collect like terms together, in order to simplify the expression

P = (x + 3x + 6x + 2x) + (2 - 17 + 5)

P = 12x - 10

(13) The perimeter of the rectangle is calculated as;

P = 2( L + B)

P = 2L + 2B

Where;

L is length of the rectangle

B is the breadth of the rectangle

P = 2 (6x + 5) + 2(3x)

P = 12x + 10 + 6x

P = 18x + 10

(14) The perimeter of the hexagon is calculated as;

P = 6L

Where;

L is length of each side

P = 6 (4x)

P = 24x
