Answer 2

Answer:

The breadth of a rectangle is 1/5th of its length. If the area of the rectangle is 125cm2. The length and breadth of the rectangle are $5cm,1cm$

respectively.

Step-by-step explanation:

A rectangle is a polygon with four sides as shown in the figure

The perimeter of a rectangle is the total linear distance along its boundary

for a rectangle with a length $l$ and breadth, $b$ the perimeter is given by the formula $P=2l+2b$

the area of the rectangle is $A=l*b$(equation $1$)

From the question, it is given that the breadth of the rectangle $b=l/5$(equation$2$)

and the area of the rectangle is $A=125cm^{2}$

substitute the values in the equation $1$ we get

$l*b=l*l/5=l^{2}/5=125\\l^{2}=125/5=25\\l=5cm$

to get breadth substitute the value of length in equation2

$b=5/5=1cm$
