1.	angle at the centre of the circle.A square field and an equilateral triangular park have equal perimeters. If the cost of ploughingthe field at rate of 5/m2 is19.210/m720, find the cost of maintaining the park at the rate ofOR
Answer» Area of square = S² total cost to plough the field = area x cost720 = S² x 5S= 12m As the perimeter is equalso, perimeter of square = perimeter of triangle4S = 3 x side of triangle48 = 3aa = 16 area of equilateral triangle =√3/ 4a²=√3 / 4 x 16²= 108.8 m² total cost = 10 x 108.8= 1088 rs Like my answer if you find it useful!

Answer»

Area of square = S²

total cost to plough the field = area x cost720 = S² x 5S= 12m

As the perimeter is equalso, perimeter of square = perimeter of triangle4S = 3 x side of triangle48 = 3aa = 16

area of equilateral triangle =√3/ 4a²=√3 / 4 x 16²= 108.8 m²

total cost = 10 x 108.8= 1088 rs
