Question

The area of a rectangular field is (2x2 -3x -20) sq.units. If the length of the field is ( 2x+5) units ,what is the breadth of the field​

Answer 1

Answer:

It is given that

Area of a rectangular field 25x

2

+20xy+3y

2

square unit

Length =5x+3y unit

We know that

Breadth = Area / Legth

So we get

=(25x+20xy+3y

2

)/(5x+3y)

=5x+y units

Now the perimeter of the rectangular field = 2 (length + breadth)

Substitute the values

=295x+3y+5x+y)

So we get

=2(10x+4y)

=20x+8y
