The length of the rectangle will be 18 cm.
The width of the rectangle will be 28 cm.
What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The perimeter of rectangle = 52 cm
An Area of a rectangle = 144 cm²
Let the length of the rectangle = l
The width of the rectangle = b
So, We get;
⇒ 2 (l + b) = 52
⇒ l + b = 26 ..(i)
And, l x b = 144 ..(ii)
Since, (l - b)² = (l + b)² - 4lb
= (26)² - 4 × 144
= 676 - 576
= 100
⇒ l - b = √100
⇒ l - b = 10 ..(iii)
Solve equation (i) and (iii), we get;
⇒ l = 18 cm
⇒ b = 28 cm
Thus, The length of the rectangle will be 18 cm.
The width of the rectangle will be 28 cm.
