Question
On a rectangular wall of length 30 metres and height 25
metres, there is a window in the shape of triangle surmounted on a square. If the base of triangle and square overlap and length of each side of the square is 6 metres and length of altitude of the triangle is 4 metres, then excluding the window, what is the surface area of the wall?Solution
Surface area of the entire wall = length × height = 30 × 25 = 750 m2 Surface area of the window = sum of surface area of the square part + surface area of the triangular part => 62 + (1/2) × 6 × 4 => 36 + 12 = 48 m2 Required surface area = 750 – 48 = 702 m2
