The length of a rectangle is 2 cm more than 3 times its width. Its area is 85 cm?. Find the
dimensions of the rectangle.

Width of rectangle = 5 cm

Length of rectangle =  17 cm

Step-by-step explanation:

Let the dimensions of rectangle:

Width of rectangle = x

Length of rectangle = 3x+2

Area of rectangle = 85 cm

We need to find dimensions of rectangle i.e length and width.

The formula used is:

Putting values and finding dimensions

Now, finding value of x using quadratic formula:

We have, a =3, b =2 and c=-85

So, we get x = 5 and x = -5.6

But since the width of rectangle cannot be negative so, we would consider x = 5

Now, the dimensions of rectangle will be:

Width of rectangle = x = 5 cm

Length of rectangle = 3x+2 = 3(5) + 2 = 15+2 = 17 cm

answer: i guess 105 degrees?
