Question

length of a rectangle is 5cm more than twice of it's breadth if area of the rectangle is 1950 Sq. cm then find out the perimeter ​

Answer 1

Answer:

so if breadth is b

then lenght is 2l+5

2l^2 +5l is 1950

2l^2 +5l-1950=0 solve the quadratic for l

and then find 2(3l+5)

which is perimeter of the figure

hope it works
