Question

The perimeter of a rectangular field is 70 m and
its length is 15 m longer than its breadth. The field
is surrounded by a concrete path as shown in the
figure. Find the area of the path.
15m
2.5 m

Answer 1

Answer:

Step-by-step explanation:

let the breadth be x

length=x+15

perimeter=2( l +b)

70=2(x +x +15)

35=2x+15

20=2x

x=10

area of path=total area-area of field

         new length=25+15+15=55m

        new breadth =10+2.5+2.5=15m

55*15m^2 - 25*10m^2

825m^2 - 250m^2

575m^2

i had made on taken 15m and 2.5m as length and breadth respectively

if its opposite then changhe the digits but the procedure will be as same

 

hope its helpful please mark me as brainliest
