Respuesta :
A rectangle has the height or breadth of [tex]X[/tex] and the width or length of [tex]7X -4[/tex] , then area of rectangle will be [tex](7X^2-4X)[/tex].
What is rectangle ?
Rectangle is a shape with four sides and having internal angles of . Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.
Area of rectangle [tex]= \text(Length \ * \ Breadth)[/tex]
We have,
Length [tex]=7X-4[/tex]
Breadth [tex]= X[/tex]
So, Using the above formula
Area of rectangle [tex]= \text(Length \ * \ Breadth)[/tex]
[tex]=X \ * \ (7X-4)[/tex]
[tex]=7X^2 - 4X[/tex]
So, the Area of rectangle is [tex]7X^2 - 4X[/tex] which is find out using above given formula.
Hence, we can say that a rectangle has the height or breadth of [tex]X[/tex] and the width or length of [tex]7X -4[/tex] , then area of rectangle will be [tex](7X^2-4X)[/tex].
