Question

Find the area of a rectangle whose length and breadth are 3.5 m and 80 cm respectively.
​

Answer 1

Answer:

area=length×breadth

Step-by-step explanation:

area of rectangle = length×breadth

A=3.5m×0.8m

A=2.8

answer.

breadth is given in cm first change it into Metre so we should divided it by 100

Answer 2

Answer:

The area of a rectangle is $2.8$ $m^{2}$.

Step-by-step explanation:

Given : Length of a rectangle = $3.5$ m

          Breadth of a rectangle = $80$ cm

To find : The area of a rectangle.

Solution :

• It is given that the length of a rectangle = $3.5$ m

          Breadth of a rectangle = $80$ cm = $\frac{80}{100} =0.8$ m

• We have to find the area of a rectangle.
• Rectangle has four sides with four right angles and the opposite sides of a rectangle are equal in length.
• The formula for area of rectangle is given by,

    Area of rectangle = $l*b$

                              = $3.5*0.8$

                              = $2.8$ $m^{2}$

• ∴ The area of a rectangle is $2.8$ $m^{2}$.
