Question

find the perimeter of a rectangle whose sides are 8cm and 5cm​

Answer 1

Answer:

Given :

• Two sides of a rectangle :- 8cm and 5cm

Find :

• Perimeter of the rectangle = ?

Answer :

• The perimeter of a rectangle is 26 cm

Step-by-step explanation:

Solution :

☆We know that,

∘ Perimeter of a rectangle = 2(length + breadth)

So, let's solve it

∘ Let the length be 8cm

∘ Let the breadth be 5cm

So,

⟹ Perimeter = 2(Length + Breadth)

⟹ Perimeter = 2(8cm + 5cm)

⟹ Perimeter = 2(13cm)

⟹ Perimeter = 2×13cm

⟹ Perimeter = 26 cm

∴ Perimeter of the rectangle is 26 cm

Answer 2

✠ Given :-

• Length of rectangle = 8 cm
• Breadth of rectangle = 5 cm

-----------------------------------------------------------------

✠ To Find :-

• Perimeter of the rectangle

-----------------------------------------------------------------

✠ Solution :-

$\large \red \bigstar \:\boxed { \bf \green{ Perimeter_{(rectangle)} = 2(L+B)} }$

Substitute values in formula

$\longmapsto \sf Perimeter = 2(8 + 5)$

$\longmapsto \sf Perimeter = 2 \times 13$

$\longmapsto \sf Perimeter = 26$

$\large \therefore \: \underline{\bf \blue{ Perimeter \: of \: rectangle \: is \: 26 \: cm}}$
