s^2 + (s+17)^2 = 25^2

s = 8

The field is 8x17 cm

What a tiny field!

cost is thus 2(8+17)cm * rs5/m * 1m/100cm = rs 2.5

How odd: since a=8,b=17

a+b = √(a^2+b^2)

My bad. I was thinking of an 8-15-17 triangle.

s=7

2(7+25)*5/100 = rs 3.20

rats! still bad arithmetic

7+17=24, not 25

you fix it
