Answer:
(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
Step-by-step 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
