Question

Find the area of the road of width 2 meter around a square field, whose side is 10 meters

Answer 1

Answer:

96 m^2

Step-by-step explanation:

14^2 - 10^2 = (14+10)(14-10)

= 24*4

= 96 m^2

Answer 2

Answer:

area of road=total area-area of field

Step-by-step explanation:

area of field=10×10=100

total area =(sides of field +4 meter road width(2+2))^2=(10+4)^2=196

area of road= 196-100=96m^2
