Another one is don't know

Answer 2

Answer:

1)

Perimiter of square = 20 cm

Hence , side = 20 / 4 = 5 cm

Now , area = ( side ) * ( side )

=) 5 * 5 = 25 cm²

2)

Area of wall = 3 * 5 = 15 m²

Area of gate = 2 * 1 = 2 m²

Area to be coloured = (15 - 2) = 13m²

Now , cost of colouring = 100 Rupees / m²

Hence , required cost = 13 * 100 = 1300 Rupees
