I WANT WITH PROCESS​​

Answer 1

Answer:

Step-by-step explanation:

Given:  Width = 5 cm , Diagonal = 13 cm

As we know that all angles of a rectangle are 90° that means it forms a right-angled triangle when divided by a diagonal.

Apply Pythagoras theorem, we can find the length using Pythagoras theorem,

l²+5² = 13²

l²+25 = 169

l² = 169-25

l² = 144

Therefore, l = 12 cm

Perimeter = 2(l+b)

= 2(12+5) ⇒2(17)

Perimeter= 34 cm
