Question

please give correct answer then i will mark you as brainlist ...​

Answer 1

Answer:

Area of rectangular plot=880m²

Length=44m

Then, Breadth=880m²/44m

=20m

Now,Perimeter=2(l+b)

=2(44+20)m

=2×64m

=138m

Cost of fencing=₹5×138m

=₹690

Hope it helps you...

Answer 2

Step-by-step explanation:

Area=length×breadth

So,breadth=area/length by algebra =880m^2/44m=20m = breadth

perimeter=2(length+breadth)

=2×(44m+20m)

=128m. (ans.)

cost of fencing :-

=perimeter×rate=₹(128×5)=₹640. (ans.)
