Question

The area of a rectangle is (x^2 + 5x – 4) square units.
Find its length if its breadth is (x - 2) units
​

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
