Area of the second rectangle is
Explanation of Solution
Given:length and breadth of both the rectangle is given.
calculation: length and breadth of first rectangle is
Area of the rectangle is given by area= length multiplied by breadth
Therefore, Area of the first rectangle is
And Area of the second rectangle is
b.
To show:howboth the rectangle is same
b.
Explanation of Solution
Given:length and breadth of both the rectangle is given.
Verification: From the above calculation we can observe that the area of both the rectangle is same because after finding the area the expression is same and if we consider any value of x
the result will be same not mater the dimension is different.
Suppose
Therefore
Hence Area of both rectangle is same.
