Perimeter of the Window:
To find the perimeter of the window, we need to calculate the sum of all the sides of the rectangular part and the semicircular top.
Rectangular Part:
The rectangular part of the window has a length of 4m and a breadth of 2m. The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the two lengths are 4m each, and the two breadths are 2m each.
So, the perimeter of the rectangular part = 4m + 4m + 2m + 2m = 12m.
Semicircular Top:
The semicircular top of the window is in the shape of a semicircle. The perimeter of a semicircle is calculated by adding the length of the curved part and the diameter.
The diameter of the semicircular top is given as 2m. The formula to calculate the circumference (perimeter) of a full circle is C = πd, where C is the circumference and d is the diameter. However, since we only have a semicircle, we need to divide the circumference by 2.
So, the length of the curved part in the semicircular top = (πd)/2 = (π * 2m)/2 = πm.
Total Perimeter:
To find the total perimeter, we add the perimeter of the rectangular part and the length of the curved part in the semicircular top.
Total Perimeter = Perimeter of rectangular part + Length of curved part in semicircular top
= 12m + πm
= 12m + 3.14m (taking π ≈ 3.14)
= 15.14m.
Conclusion:
The perimeter of the window is approximately 15.14 meters.
