Question

I)A rectangular lawn of sides 400 m and 300 m is surrounded by a path of width 3 m surrounding it .Find the area of the path
II)Find the radius of a circle with circumference 176 cm

Answer 1

Answer:

Step-by-step explanation:

Area of the lawn=400 x 300=120,000

Length=400 + 3 +3 =406m

Breadth= 300 + 3 +3=306m

Area= 406 x 306 =124,236sq m

Area of the path= 124,236 x 120,000

                         = 14,908,320,000sq m

Answer 2

Answer:

1. 4236 sq. m

2. 28 cm

Step-by-step explanation:

1)Area of rectangular lawn=400 x 300 = 120,000

Width of path = 3m

Area of lawn including path = (400+3+3) x (300+3+3) = 406 x 306= 124,236 sq.   m

Area of path = 124,236 - 120,000 = 4236 sq. m

2) Let the radius be = r

Circumference =  2πr

Circumference= 176 cm

2πr = 176 cm

2 x 22/7 x r = 176

22/7 x r= 88 (divide 2 from 176)

7 x r = 4 (divide 22 by 88)

r = 4 x 7

r = 28 cm
