Question

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

Answer 1

Answer:

4236 sq. m

Step-by-step explanation:

Length of rectangular lawn = 400 m

Breadth of rectangular lawn = 300 m

Area of rectangular lawn = 400 * 300 = 120000 sq. m

Width of path = 3 m

Length of rectangular lawn including path = 400+3+3 = 406 m

Breadth of rectangular lawn including path = 300+3+3 = 306 m

Area of rectangular lawn including path = 406 * 306 = 124236 sq. m

Area of path = Area of rectangular lawn including path - Area of rectangular lawn

Area of path = 124236 – 120000

Area of path = 4236 sq. m

Hence the area of the path = 4236 sq. m

Answer 2

Answer:

Step-by-step explanation:

Length of rectangular lawn = 400 m

Breadth of rectangular lawn = 300 m

Area of rectangular lawn = 400 * 300 = 120000 sq. m

Width of path = 3 m

Length of rectangular lawn including path = 400+3+3 = 406 m

Breadth of rectangular lawn including path = 300+3+3 = 306 m

Area of rectangular lawn including path = 406 * 306 = 124236 sq. m

Area of path = Area of rectangular lawn including path - Area of rectangular lawn

Area of path = 124236 – 120000

Area of path = 4236 sq. m

Hence the area of the path = 4236 sq. m
