Solution:
Let,
The width of the rectangular field is x meter
∴ The length of the rectangular field is 2x + 10 meter
ATQ,
2(2x + 10 + x) = 104
⇒ 3x + 10 = 52
⇒ 3x = 42
∴ x = 14
∴ The area of that field is = (2x + 10) × x = (2 × 14 + 10) × 14 = (28 + 10) × 14 square meters
= 38 × 14 square meters = 532 square meters
