Question

square and rectangular field with measurement as given have same perimeter [60] [80].Which field has larger area​

Answer 1

Answer:

Given: The side of a square = 60 m

And the length of rectangular field = 80 m

According to question,

Perimeter of rectangular field

= Perimeter of square field

= 4 side

m

Now Area of Square field

=

= = 3600 m2

And Area of Rectangular field

= length breadth = 80 40

= 3200

Hence, area of square field is larger.

Answer 2

Step-by-step explanation:

Perimeter of a rect.= 2(l+b)

= 2(60+80)

= 2×140

=280

area of a rect= l×b= 60×80= 4800 square units

perimeter of a square= 4×side

280= 4×s

s= 280/4= 70

area of a square= s²= 70²= 4900 square units

Therefore area of a square exceeds area of a rectangle by 100 square units.

hence, square has a larger area
