Question

a path of uniform width 5 metre runs around the inside of a rectangular field of dimenslons 40 metre by 30 metre find the area of the path​

Answer 1

Given:

☛ width of path = 5 m

☛ dimensions of Rectangular field = 40 × 30

To Find:

☛ area of path

Solution:

☛ Length of path = length of Rectangular field - (2 × width of path)

➜ length of path = 40 - (2×5)

➜ length of path = 40 - 10

➜ length of path = 30 m

☛ Breadth of path = breadth of Rectangular field - ( 2 × width of path )

➜ breadth of path = 30 - ( 2 × 5)

➜ breadth of path = 30 - 10

➜ breadth of path = 20 m

☛ Area of path = Area of Rectangular field - area of field left excluding the path

➜ 40 × 30 - 20 × 30

➜ 1200 - 600

➜ 600

Answer is 600 m²
