the length and breadth of a rectangular field are 20 cm and 12 CM respectively . Find its area and hence convert its unit into SI system
Answers
Answer:
Area of rectangle
Area can be described as the space occupied by a flat shape. Area is measured in square units.
The basic formula for area of a rectangle is equal to the product of length and breadth. i.e.
\implies \boxed{Area_{(rectangle)} = l \times b}⟹
Area
(rectangle)
=l×b
Where, l denotes length of rectangle and b denotes breadth of rectangle.
Length and breadth are given in the question, that is,
length, l = 20cm
breadth, b = 12cm
And we have to find the area of rectangle.
By using the formula and substituting the known values, we get:
\begin{gathered}\implies Area_{(rectangle)} = 20 \times 12 \\ \\ \implies \boxed{Area_{(rectangle)} = 240}\end{gathered}
⟹Area
(rectangle)
=20×12
⟹
Area
(rectangle)
=240
Now, let's convert the unit into SI unit. We know that, cm² is CGS unit so we need to convert it into m².
We know that, to convert cm into m we have to divide the value by 100.
\implies \dfrac{240}{100} = \boxed{\bf{2.4 \: m^2}}⟹
100
240
=
2.4m
2
Hence, the area of rectangle is 2.4 m².
