c) square field will have greater area.

please answer as fast as possible ​

Answer 1

$\huge{\underline{\underline{\boxed{\sf{\red{Aɴsᴡᴇʀ\: ࿐}}}}}}$

length of rectangle=400m

breadth of rectangle=100m

a) Area of rectangle=l×b

= 400×100

=40000m²

Side of square=200m

Area of square=(side)²

= (200)²

=40000m²

Yes, they have the same area.

b) perimeter of rectangle=2(l+b)

=2(400+100)

=1000cm

perimeter of square= 4×side

=4×200

=800cm

Hence, perimeter of rectangle is greater than that of square

So rectangle requires more fencing by 1000-800=200cm

rectangle requires more fencing by 200cm.

Answer 2

Answer:

length of rectangle=400m

breadth of rectangle=100m

a) Area of rectangle=l×b

Yes, they have the same area.

b) perimeter of rectangle=2(l+b)

=1000cm

perimeter of square= 4×side

=4×200

=800cm

Hence, perimeter of rectangle is greater than that of square

So rectangle requires more fencing by 1000-800=200cm

rectangle requires more fencing by 200cm.
