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.
5 m
2.5 m​

Answer 1

Answer:

The answer is 250 m2

Step-by-step explanation:

p = 70m

l = 15 + b

A = ?

We have,

p = 2 (l+b)

70 = 2 ( 15+b+b)

70 = 2x15+2x2b

70 = 30+4b

4b = 70-30

b = 40/4

b= 10m

l = 15+b

l= 15+ 10

l = 25m

A = lxb

A= 25x10

A = 250 m2
