Question

a path of uniform width 3m , runs around the outside of a square feild of side 21m . find the area of the path?​

Answer 1

Answer:

288m^2

Step-by-step explanation:

According to the given information the figure will be as shown alongside.  

Clearly, length of the square field excluding path = 21 m.

Area of the square side excluding the path = 21 x 21 = 441 m2  

Again, length of the square field including the path = 21 + 3 + 3 = 27 m

Area of the square field including the path = 27 x 27 = 729 m2  

Area of the path = 729 – 441 = 288 m2
