Question

area of square field is 3600 metre square a rectangle whose length is twice its width has perimeter equal to the perimeter of square field find the area of rectangular field​

Answer 1

Answer:

side of square is 15.

so, length and breadth of rectangle will be 20 and 10 respectively.

so, Area of rectangle will be 200.

Answer 2

❤❤❤plz plz plz mark me brainlist

Step-by-step explanation:

Side of square field =√area

=√3600msq.

=60m

Perimeter of square field =4xside

=4x60m

=240m

Let the breadth be p

Then the length =2p

According to question the perimeter of square and rectangle is equal

Therefore ,

Perimeter of rect.. =perimeter of sq.

2(l+b)=240m

=>2(2p+p)=240m

=>3p=240/2

=>3p=120

So p=120/3

=40m

Now subtituing the value of p

Length of rect.. =2p

=2x40m

=80m

Breadth of rectangle =p

=40m
