Question

The length and the breadth of a rectangle is 8 cm and 5 cm respectively. Find its perimeter and area.​

Answer 1

Step-by-step explanation:

Given that

Length of rectangle is 8cm

Breadth is 5cm

To find

Perimeter and Area

Solution

$perimeter = 2(l + b) \\ = 2(8 + 5) \\ = 26cm$

perimeter is 26cm.

$area = l \times b \\ = 8 \times 5 \\ = 40 {cm}^{2}$

area is 40cm sq.

Answer 2

To find : area and perimeter of rectangle .

Given : length $=8 \mathrm{~cm}$ and breadth $=5 \mathrm{~cm}$

Solution :

• According to question we are given that length and breadth of rectangle are $8 \ cm$ and $5\ cm$ respectively. We have to find area and perimeter of rectangle .  

• To find area we use following formula -

        Area of rectangle $=l \times b$

• Substituting the values we get,

        Area of rectangle $=8 \mathrm{~cm} \times 5 \mathrm{~cm}$

                                      $=40 \mathrm{~cm}^{2}$

• To find perimeter we use following formula -

      Perimeter of rectangle = $2 ( l + b )$

                                              $=2 ( 8 + 5 ) \ cm \\= 2\times 13 \ cm \\= 26 \ cm$

Hence, area and perimeter of rectangle are $40 \ cm ^{2}$ and $26\ cm$ respectively.
