Question

The width of a rectangle is 5 cm and its diagonal is 13 cm What is its perimeter? ​

Answer 1

Given,

Width of a rectangle = 5cm

Diagonal = 13cm

length = 13²-5² = 169-25

$\sqrt{144} = 12cm$

As, we know that

Perimeter of a rectangle = 2(l+b)

= 2(12+5) = 2×17 = 34cm

Answer 2

Answer:

Width of a rectangle = 5cm

Diagonal = 13cm

Length = 13²-5² = 169-25 = √144 = 12 cm

Perimeter of a rectangle = 2(l+b)

= 2(12+5) = 2×17 = 34cm
