Answer 2

Answer:

$\bold\red{Question}$

Find the perimeter of the rectangular field whose length is 4 times its wide and which has an area equal to 30976cm square.

$\bold\red{Given}$

Let the breadth be x

Length= 4 × x = 4x

Area = 30976 cm²

$\bold\red{To\:Find}$

We have to find the perimeter of the rectangular field.

$\bold\red{Solution}$

Let the breadth be x

Length= 4 × x = 4x

Area = 30976 cm²

•°• 4x × x = 30976

= ${x}^{2} = \frac{30976}{4}$

x² = 7744

x = 88
