Question

Fencing is laid along the
side of a square plot of area
225m2. If the cost of fencing
per metre is Rs.2.50, find the
cost to lay the fencing. ​

Answer 1

Area of square=side^2=225m^2

So,

Side of plot=underroot(225)=15m

Perimeter of plot=15×4=60m

Rate of fencing=2.5rupees

So, the cost of fencing=2.5×60rupees=150rupees

Answer 2

Answer:

area of square =side^2 or side×side

area of square =225

• now, side=underoot 225
• side=15m
• fencing is done on perimeter so we will find perimeter which is 4×side
• perimeter=4×15
• =60 m

now cost =60×2.50

=RS150.00
