Question

178 per m2.
48 m and 30 m. If
A path 2 m broad is to be built outside a
Find the cost of construction of the path at
square park of side 18 m along its boundary.​

Answer 1

Answer:

★The total cost of construction is Rs. 25276.

Step-by-step explanation:

Since we have given that

Side of square = 18 m

Width of square = 2 m

So, Side of outer square = 18+2+2=18+4=22 m

So, Area of square is given by

side²=18²=324 m²

Area of outer square is given by

Side²=22²=484m²

So, Area of the path would be

484−342

=142 m²

Cost per sq. m = Rs. 178

So, Total cost would be

178×142=Rs. 25276

★Hence, the total cost of construction is Rs. 25276.
