You just have to assume one side be x.
Other side = x+5 cm
Now,
x(x+5) = 150
i.e. x^2 +5x -150= 0
By applying quadratic formula, you will get the answer.
i.e. x = 10, -15.
As sides can't be negative.
So,sides will be 10 and 15 cm.
Other side = x+5 cm
Now,
x(x+5) = 150
i.e. x^2 +5x -150= 0
By applying quadratic formula, you will get the answer.
i.e. x = 10, -15.
As sides can't be negative.
So,sides will be 10 and 15 cm.

Let other side of rectangle be x
and one side of rectangle be x+5
a/q
area of rectangle = 150
x(x+5)= 150
x^2+5x-150=0
x^2+15x-10x-150=0
x(x+15)-10(x+15)=0
(x+15)(x-10)=0
x=10,-15
therefore,
other side of rectangle = 10
one side of rectangle = 10+5=15
and one side of rectangle be x+5
a/q
area of rectangle = 150
x(x+5)= 150
x^2+5x-150=0
x^2+15x-10x-150=0
x(x+15)-10(x+15)=0
(x+15)(x-10)=0
x=10,-15
therefore,
other side of rectangle = 10
one side of rectangle = 10+5=15
