Question

The length of a rectangle is 8 m less than thrice its width. If area of the rectangle is 1675 sq m them find the length and width of the rectangle brainly

Answer 1

Step-by-step explanation:

Let breadth of the rectangle = x

length of the rectangle = 3x-8

Area of rectangle = l×b

1675 = x(3x-8)

1675 = 3x^2-8x

3x^2-8x-1675 = 0

a = 3, b =-8, c = -1675

x = (-b±√b^2-4ac) / 2a

D = √b^2-4ac

D = √64-20100 < 0

Hence, D is imaginary

So, it will give imaginary values of x
