Question

The length of a rectangular field is four times its breadth. If the area of the field is 30,976 square units, find the length of its sides.

Answer 1

Answer:

352 units

Step-by-step explanation:

Given : Length = 4 × Breadth

Suppose Breadth = x unit

then, Length = 4x unit

Now,

Area = 30,976 square units

=> Length × Breadth = 30,976 square units

=> 4x × x = 30,976 square units

=> 4x² = 30,976 square units

=> x² = (30,976 ÷ 4) square units

=> x² = 7744 square units

=> x² = (88)² square units

=> x = 88 units

=> 4x = 4 × 88 units

=> 4x = 352 units

Here, Length = 4x = 352 units

Answer 2

Answer:

length = 4 z = 4 x 88 = 352 units

and breadth = z = 88 units

Step-by-step explanation:

let breadth = z

length = 4 z

area = 30 , 976 = l x b

30,976 =4z [ z ]

30,976 =  4 $z^{2}$

30,976 / 4 = $z^{2}$

7744 = $z^{2}$

$\sqrt{7744} =$ z =  88

here , length = 4 z = 4 x 88 = 352 units

and breadth = z = 88 units
