Which field has a larger area
\huge{\underline{\purple {★solution:-}}}
★solution:−
square:
side of square=60m
formula used for area:
(side)^2
area of square=(60)^2
=3600m^2
formula used for perimeter:
(side)×4
perimeter of square=4(60)
=240m
rectangle:
length=80m
let breadth=B
formula used for perimeter:
2(l+B)
perimeter of rectangle=240m
equation for Breadth:
240=2(80+B)
=>240/2=80+B
=>120-80=B
=>B=40
Breadth=40m
formula used for area:
L×B
area of rectangle=80×40
=2400m^2

dekh bro square ki sab side brabr hoti hai to perimeter of square 4×60=240-rectangle ki do side brabr hoti hai 80+80=160
240-160= 80
do side brabr kr de samne ki
80/2=40
