Question

which has a greater area a rectangle of 12 cm long and 6.2 cm wide or a square of 9 CM side what is the difference in their areas
$l \times b$
​

Answer 1

Explanation:

there is a difference of 6.6cm^2

Answer 2

Square has a greater area. Difference of area is 6.6$\mathbf{(cm^{2})}$

Explanation:

1. Given data about rectangle

  Length of rectangle (L) = 12   cm

  Breadth of rectangle (B) = 6.2   cm

  Area of rectangle ($A_{R}$) = Length×Breadth

  Area of rectangle ($A_{R}$) = 12×6.2 =74.4 $\mathbf{(cm^{2})}$      ...1)

2. Given data about square

   Side of square (a) = 9    cm

   Area of square ($A_{S}$) = Side× Side

   Area of square ($A_{S}$) = 9× 9 = 81  $\mathbf{(cm^{2})}$       ...2)

3. We see that area of square is more than area of rectangle.

4. Difference between area of square and area of rectangle is

  Difference of area = Area of square - Area of rectangle

  Difference of area =81 - 74.4 = 6.6   $\mathbf{(cm^{2})}$
