Question

how to find area when perimeter in given

Answer 1

for sq.
if P=s (s is the perimeter)
then side= (s/4)
and area = side*side=(s^2/16)

Answer 2

here's ur answer....

if it's a square, then divide the perimeter with 4 as we know all the sides of square are equal.then find the area by multiplying side×side.

fir equilateral triangle divide the perimeter with 3. a equilateral triangle have 3 equal sides therefore we will divide the perimeter with 3.
then find area by the formula

for rectangle we will find by the given process:-

let perimeter be 15cm and length be 4cm

2(l+b)=15cm

2(4+b)=15cm

8+2b=15cm

2b=15-8

2b=7/2

b=3.5cm

now find the area by multiplying l×b.

hope this helps...
