Anjana Khatri answered |
Let x and (16 - x) are two parts of 16 where (16 - x) is longer and x is smaller .
A/C to question,
2 * square of longer = square of smaller + 164
⇒ 2 * (16 - x)^2 = x^2 + 164
⇒ 2 * (256 + x^2 - 32x ) = x^2 + 164
⇒ 512 + 2x^2 - 64x = x^2 + 164
⇒ x^2 - 64x + 512 - 164 = 0
⇒ x^2 - 64x + 348 = 0
⇒x^2 - 58x - 6x + 348 = 0
⇒ x(x - 58) - 6(x - 58) = 0
⇒(x - 6)(x - 58) = 0
⇒ x = 6 and 58
But x ≠ 58 because x < 16
so, x = 6 and 16 - x = 10
Hence, answer is 6 and 10
