Question

a charity trust decide to build a prayer hall having a carpet area of 300 square metres with its length one metre more than twice its breadth find the dimension of the prayer Hall​

Answer 1

Answer:

Step-by-step explanation:

the breadth is x

and the length is y

now by the condition

y = 2x + 1

now the given area is 300m²

by the condition

xy = 300

x(2x + 1) = 300

2x² + x -300 = 0

2x² + 25x - 24x - 300 =0

2x² -24x + 25x -300 =0

2x(x-12) + 25(x - 12) =0

x =12

now the lenght = 2 x 12 +1

                           = 25

Answer 2

Answer:

Length = 25

Breadth = 12
