To find the perimeter, we add up all the sides:
Perimeter = 7 cm + 5 cm + 5 cm + 5 cm + 5 cm + 7 cm + 18 cm
Perimeter = 52 cm
To find the area, we need to know the shape of the figure. Assuming it is a hexagon (a six-sided figure), we can divide it into equilateral triangles to find the area.
We know that the length of each side is 5 cm, so we can use the formula for the area of an equilateral triangle:
Area = (sqrt(3)/4) x side^2
Area of one equilateral triangle = (sqrt(3)/4) x 5 cm^2
Area of one equilateral triangle = 6.25 cm^2
Since the hexagon is made up of six equilateral triangles, we can find the total area by multiplying the area of one triangle by six:
Area = 6 x 6.25 cm^2
Area = 37.5 cm^2
Therefore, the area of the hexagon is 37.5 cm^2.
