Question

answer the question​

Answer 1

Answer:

perimeter=400m=2(l+b)

l=x+26. b=x

2(2x+26)=400

4x+52=400

4x= 348

x=87

length=113m

breadth =87m

area=l×b

=113×87

=9831m^2

Answer 2

Answer:

length=113

breadth=87

area=9831msquare

Step-by-step explanation:

let the breadth and length be x and x+26 respectively.

perimeter=400m

therefore,

          2 x [x+(x+26)]=400

         2 x [x+x+26]=400

            4x+52=400

            4x=400-52

              x=400-52÷4

             x=348÷4

             x=87

so, length=87+26=113m

     breadth=87m

area=length x breadth=113 x 87=9831msquare
