Question

A 4m wide path runs around a field of length 130m and width 85m. Find the area of the path.

Answer 1

Answer:

Step-by-step explanation:

Length becomes 130-2*4=130-8=122

Breadth =85-4*2=85-8=77

Now area =l*b=122*77 =

9394

Answer 2

The area of the path is 1784 m².

Given:

Length of field= 130m

Width of field= 85m

Width of path= 4m

To find: Area of the path

Solution:

Total area including area of path = Total length x Total width

We know,

Total length= length of field + 2(width of park)= 130 + 2(4)= 138m

Total width= width of field + 2(width of park)= 85 + 2(4)= 93m

⇒Total area= 138 x 93 = 12,834 m²

Now,

Area of field= Length of field x Width of field= 130x85 = 11,050 m²

⇒Area of path = Total area - Area of field = 12834 - 11050 = 1784 m²

∴The area of the path is 1784 m² Answer
