  1. A window is made up of a square portion and an equilateral triangle portion above it. The base of the triangular portion coincides with the upper side of the square. If the perimeter of the window is 6 m, the area of the window in m² is
    1. 1.43
    2. 2.06
    3. 2.68
    4. 2.88
Correct Option: B

The possible window will be as follows:

Perimeter of window = 5x = 6m
x = 1.2 m
So area of window = Area of triangle + Area of square

=
3
x² + x²
4

=
3
(1.2)² + (1.2)²
4

= 2.06 m²
