the area of rectangle is 324 m2 and breadth is 18m find the length of rectangle in cm2
Answers
theThe area of a square field is 324 metres square then the perimeter is 7200 cm
Solution:
Given that area of square field is 324 meter square
To find: perimeter in centimeter
The area of square is given as:
\text{area of square } = a^2area of square =a2
Where "a" is the length of side
Substituting area = 324 we get,
\begin{gathered}324 = a^2\\\\a^2 = 324\\\\a = \pm18\\\\\end{gathered}324=a2a2=324a=±18
Ignoring negative value, we get
a = 18 m
The perimeter of square is given as:
Perimeter = 4a
Where "a" is the length of side
Substituting a = 18 m, we get
Perimeter = 4(18) = 72 m
Finding perimeter in centimeter
We know that,
1 m = 100 cm
Therefore,
72 m = 72 x 100 = 7200 cm
Thus perimeter of square is 7200 cm
Answer:
18 m
Explanation:
Area of a rectangle = length × breath
324 = x × 18
324\18 = x
18 = x
therefore , length is 18 m
