Question

The length of the rectangle is 12 cm and diagonal is 13 cm find the perimeter

Answer 1

by Pythagoras triplet 12^2+5^2 = 13^2
therefore b=5
perimeter of rectangle=2(l+b)
on putting the values = 2(12+5)
17×2=34

Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

STEP 1: Find The breadth:

a² + b² = c²

12² + b² = 13²

b² = 13² - 12²

b² = 25

b = 5

The breadth is 5 cm

.............................................................................................

STEP 2: Find the perimeter:

Perimeter = 2 ( Length + Breadth)

Perimeter = 2 (12 + 5) = 2(17) = 34 cm

.............................................................................................

Answer: The perimeter is 34 cm
