Answer 1

Answer:

plz mark me as brainlist

Step-by-step explanation:

length is 7 cm

breadth is 10 cm

Area of a rectangle=l×b=7×10=70cm²

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,

A rectangle is a four-sided two-dimensional plane figure.

The rectangle is a type of parallelogram that has all of its angles equal.

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 $70cm^2.$
