A rectangle has a base length of x+2 and a height of x+4. Work out an expression for the area of the shape?
Multiply the two binomials.
x^2 + 2x + 4x + 8 simplify from here and that will be your answer.
area = l x w
To find the area of a rectangle, we simply multiply its length by its width. In this case, the base length of the rectangle is given as x + 2, and the height is given as x + 4.
Therefore, the expression for the area of the rectangle is:
Area = (x + 2) * (x + 4)
We can expand this expression further:
Area = x*x + 2*x + 4*x + 8
Simplifying this expression, we get:
Area = x^2 + 6x + 8
So, the expression for the area of the rectangle is x^2 + 6x + 8.
To find the area of a rectangle, you need to multiply its base length by its height. In this case, the base length is x + 2 and the height is x + 4.
So, the expression for the area of the rectangle is:
Area = (base length) * (height)
= (x + 2) * (x + 4)
Now, let's simplify this expression:
Area = x * x + x * 4 + 2 * x + 2 * 4
= x^2 + 4x + 2x + 8
= x^2 + 6x + 8
Therefore, the expression for the area of the rectangle is x^2 + 6x + 8.
