Question

Find the perimeter of Rectangles Whose sides are :
7 cm and 5 cm
11 cm and 14 cm
17 cm and 33 cm​​

Answer 1

Given : 7 cm and 5 cm,11 cm and 14 cm,17 cm and 33 cm.

To Find : Perimeter of Rectangle.

Formula Used : 2(l+b)

⠀⠀⠀⠀⠀___________________________

❍7 cm and 5 cm

We know that,

Perimeter of Rectangle = 2(l+b)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2(7+5)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 24 cm

${\underline{\textsf{Hence,Perimeter \ of \ rectangle \ is {\textbf{24 cm}}}}}$.

❍11 cm and 14 cm

We know that,

Perimeter of Rectangle = 2(l+b)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2(11+14)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 50 cm

${\underline{\textsf{Hence,Perimeter \ of \ rectangle \ is {\textbf{50 cm}}}}}$.

❍17 cm and 33 cm

We know that,

Perimeter of Rectangle = 2(l+b)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 2(17+33)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = 100 cm

${\underline{\textsf{Hence,Perimeter \ of \ rectangle \ is {\textbf{100 cm}}}}}$.
