Question

find the area of a rectangle whose length is 7cm and breadth is 10cm​

Answer 1

$\large{\boxed{\boxed{\sf{firstly,~ let~ understand~ the~ concept}}}}$

★ Here, length of rectangle is 7 cm and breadth of rectangle is 10 cm. We have to find the area of rectangle.

⠀

Given:-

• Length of rectangle = 7 cm.
• Breadth of rectangle = 10 cm.

⠀

To find:-

• Area of a rectangle?

⠀

Solution:-

⠀

★ Formula used:-

$\star{\boxed{\sf{\orange{Area~ of~ rectangle = Length × Breath}}}}$

⠀

$\large{\tt{\longmapsto{7 \times 10}}}$

⠀

$\large{\tt{\longmapsto{70~ cm^2}}}$

⠀

Hence, the area of rectangle is 70 cm².

Answer 2

Answer:

The area of a rectangle is $70cm^2.$

Step-by-step explanation:

As per the data given in the above question,

Given that:-

The length of a rectangle = $7cm$

The breadth of a rectangle = $10cm$

We have to find the area of a rectangle,

The area of a rectangle is calculated by multiplying the length and breadth of a rectangle.

Here we have to use the formula of the area of a rectangle,

i.e., $A = l\times b$

Where, l = length  

            b = breadth

Given:- l = $7cm$ and b = $10cm$

Substitute the given values of length and breadth in the above formula we get,

$A = 7\times 10$

Multiplying $7$ by $10$, we get

$A = 70cm^2$

Hence, the required solution is $70cm^2.$
