A.15x+1
B.56x^2+8x
C.56x+8
D.15x^2+9x

I don't know what to do please help me. I don't understand.

The area of a rectangle

= length x width
= 8x(7x+1)

expand to see which matches

btw, it is a rectangle not an angel

To find the area of a rectangle, you need to multiply its length by its width. In this case, the length is given as (7x + 1) and the width is given as (8x).

To calculate the area, you can use the formula:

Area = length * width.

So, the area of the rectangle would be:

Area = (7x + 1) * (8x).

You can simplify this expression by using the distributive property of multiplication, which states that a(b + c) = ab + ac.

Applying this property to the expression, we expand it as follows:

Area = 7x * 8x + 1 * 8x.

Simplifying further:

Area = 56x^2 + 8x.

Therefore, the area of the rectangle is given by the expression 56x^2 + 8x.

So, the correct answer is B) 56x^2 + 8x.
