Question

a square and a rectangle plot of land have the same perimeter. The square has a side of 30m.

Answer 1

if the side of square =30cm
perimeter of square =4*30
=120cm
it is given that,
perimeter of square =perimeter of rectangle
so,
the perimeter of rectangle =120cm
2(l+b)=120
2*30+2b=120
60+2b=120
2b=120-60
b=60/2
b =30cm
