বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
Given that, Diagonal of rectangle, d = 13
Width, w = 5
We know,
Pythagorean theorem, l2 + w2 = d2
⇒ 132 = l2 + 52
⇒ 169 = l2 + 25
⇒ l2 = 169 - 25
⇒ l2 = 144 = 122
∴ l = 12
∴ length In a rectangle is, l = 12
Perimeter of a rectangle, P = 2(l + w)
= 2(12 + 5) = 2 × 17 = 34
So the perimeter of the rectangle is 34.
