Question

The perimeter of a rectangular field is 70 m and its length is15 longer than its breadth. The filed is surrounded by a concrete path as shown in the figure. Find the area of the path.
5 m

⬜
2.5m

Answer 1

Answer:

Perimeter of rectangle =2(l+b)

70=2(l+b)

Let,B=X

L=X+15

THEN

2(X+15+X)=70

4X+30=70

4X=70-30

4X=40

X=40/4

X=10

Area of its path =l(b)

=l=25+2. 5+2.5

B=10+2. 5+2.5

=30(20)

=600m
