Answer 1

Answer:

Step-by-step explanation:

1) Area of rectangle is L x B

540=27 x breadth

breadth =540/27

breadth =20m

perimeter = 2x(l+b)

=2x(47)

=  94 meter is the perimeter

2) Area of square park = S x S

=60x60= 3600m²

area of square = Area of rectangle

3600 =90 x b

b = 3600/90=40m is the breadth of the rectangular park

3) Circumference of circle  is 2πr =2 x 22/7 x 35 =2 x 22 x 5 = 220cm

4) ) Circumference of circle  is 2πr =2 x 22/7 x  2.1 = 2 x 22 x 0.3 =13.2m per hour for 2 hours 13.2x2 = 26.4m

340=lx17

l=340/17

l = 20

Perimeter = 2x(l+b)

=2x(37)

=74m

Cost = 74x5.70= 421.8Rs

we need to find the perimeter of the rectangle for the circumference  of the circle

=2x(18.7+14.3)

2x33

=66cm is the circumference of the circle

66/3.14x2

=10.5cm

Area = 346.36cm² is the area of the circle so formed
