Let total no. of bricks(22.5 cm ×10 cm) = 'n'
Area acquired by a brick = 22.5 × 10  = 225 cm² = 0.0225 m²
Area of the street lane = (length)×(breadth)
                                    =  240 × 12 m²
A/q,
             Total  area of the lane = n×(area of 1 brick)
⇒           240 ×12 =n(0.0225)
⇒                    n = (240×12×10000)/225
⇒                    n = 128000
 Total no. of bricks required to pave the whole lane = 128000
