Question

The length and breadth of a rectangular hall are ( x + 5 ) mand x m respectively . The carpet area of the hall is 84 m² write he quadratic equation to find the value of x .​

Answer 1

ANSWER

84m2 x(x+5)=84

EXPLANATION

let the breadth be x m so the lenght will be( x+5)m according to the given condition area of rectangle = 84m2 x(x+5)=84

hope this helps you!

Answer 2

Answer:

x² + 5x - 84 = 0.

Step-by-step explanation:

Length = x+5 and Breadth = x.

Area = 84 sq. m

Area = Length + Breadth

84 = x(x+5)

Therefore the quadratic eq. is x² + 5x - 84 = 0.
