answer as fast as you can​

Answer 1

Answer:

Step-by-step explanation:

Let width be X

Length be 4X

According to question

X×4X=20736

4X^2=20736

X=72

Length=4×72=288m

Width=72m

Perimeter= 2(288+77)

=2×360

=720m

Answer 2

____Hey mate here is your answer___

_______________________________

Lets the width of the rectangular field be X

Now, Length of the rectangular field is 4X

Here , Area is 20736 m²

According to the problem,

Area of the rectangular field = Length × Breadth

=> 20736 = X × 4x

=> 4x² = 20736

=> x² = 20736 ÷ 4

=> x² = 5184

=> X = √5184

=> X = 72

________________________________

Now ,Length be 4× 72

= 288 m

Breadth be 72 m

So, perimeter of the rectangular field = 2(L+b)

=2 ( 288 + 72 ) m

= 2× 360 m

= 720 m .

°: The perimeter of the rectangular field is 720 m....
