Area of PQRS = l x b = 700 × 300

= 2,10,000 sq m

Area of cross Roads = Area of KLMN abcd – 1, 2, 3, 4

= 300 × 10 + 700 × 10 – 10 × 10

= 3000 + 7000 – 100

= 10,000 – 100 = 9,900 sq mts

Area of the park excluding the cross roads =  2,10,000 – 9,900

= 2,00,100 sq mts.

Area in hectares = \(\frac{2,00,100}{10,000}\) = 20.01 hectares
