Answer 2

★ Given :

The length and breadth of a rectangular field are in the ratio 3:2 . the area of field is 13502.

★ To Find :

Perimeter Of the Field.

★ Solution :

✏ Let Length = 3x

✏ Let Breadth = 2x

Area = Length × Breadth

➞ 1350 = 3x × 2x

➞ 1350 = 6x²

➞ x² = 1350/6

➞ x = ⎷225

➞ x = 15 cm

✏ Length = 15 × 3

= 45 cm

✏ Breadth = 15 × 2

= 30 cm..

Now,

Now, Finding The perimeter

Perimeter = 2 (L + B)

➞ 2 ( 45 + 30)

➞ 2 × 75

➞ 150.

∴ Perimeter of Rectangle is 150 cm.
