Question

if area of rectangle field field is21x^2-7xand one of side is7x, what is its other side​

Answer 1

Answer:

Area of rectangular field 21x^2 -7x

side is 7x

As we know that area of rectangle is L × B

So, lets say breadth will be area/ length

that is 21x^2 - 7x divided by 7x

So, by taking 7x common from the given area,

7x( 3x - 1) / 7x

7x gets cancelled out and we are left with 3x - 1

so the other side of the rectangle is 3x - 1
