Question

3. Calculate the area of
rectangle if one square
represents an area of 1 cm2

Answer 1

Answer:

2$cm^{2}$

Step-by-step explanation:

first you have to explain the question that how many squares are there in the question .

if there are 2 squares then,

area of rectangle= l×b

                            = 1×2 = 2$cm^{2}$

Answer 2

Answer:

Area of rectangle formed = 2$cm^{2}$  

Step-by-step explanation:

Minimum, two units of the squares are required to form a rectangle.

Side of square = 1 cm

Forming a rectangle by 2 squares,

Now after formation of the rectangle,

length of rectangle formed = 2 cm

breadth of rectangle formed = 1 cm

Applying, formula of area for rectangle, that is,

area of rectangle= l × b

where, l =length and b= breadth

area of rectangle = length × breadth

area of rectangle = 2 cm × 1 cm

area of rectangle =2$cm^{2}$  

Therefore, area of rectangle formed from the two units of square of side 1 cm  = 2$cm^{2}$
