Answer 1

Answer:

HINT = AREA OF PARK- uncobbled area = cobblesarea

NOW let we find are of apark

area of rectangle = l*b

area of the park = 76*36

                            =   2736cmsquare

now we find uncobbled area

8 m wide path inside

So inside area  = ( 76 - 2*8)  * ( 58 - 2 * 8)

= 60 * 42

= 2520 m²

Area of Path = 4408 - 2520 = 1888 m²

Cost of Laying cobble stone = Rs 35 m²

Cost of Laying cobble stone 1888 m² = 35 * 1888 =  Rs 66080
