Question

find the perimeter of a rectangular field whose length is 4 times it's width and which has area equal to 20736 sq.m​

Answer 1

Answer:

=720 m

Step-by-step explanation:

let breadth be B

so length = 4B

Area of rectangular field = L × B = 20736

=> 4B × B = 20736

=> 4×B2 = 20736

=> B2 = 20736/4

=> B2 = 5184

=> B = _/5184

=> B = 72

So breadth = 72, length = 4×72= 288

Now perimeter = 2× ( L + B )

= 2×(288 + 72)

= 2 × 360

= 720m
