Question

The length and breadth of a rectangle are in the ratio 7:5 and the perimeter is 1200 cm. Find the area of the rectangle.
​

Answer 1

Step-by-step explanation:

Here is your solution

Given :-

The ratio of length and breadth of the given rectangle is 7:5

Let the length and breadth be 7x and 5x .

perimeter of the rectangle = 2 (l + b)

=>336= 2(7x+5x)

=>336= 24x

=>14=x

length = 7x =7×14=98

and breadth = 5x = 5×14=70

aarea of rectangle = length × breadth

=>l×b

=> 98×70

=>6860cm^2
