8
5x+2

The expression for the area of the rectangle is given by multiplying the length and width of the rectangle. In this case, the length is 8 and the width is 5x + 2. So, the expression in simplified form for the area of the rectangle is:

Area = 8 * (5x + 2) = 40x + 16

Write an expression in simplified form for the area of the rectangle.


10
3x+5

The expression for the area of the rectangle is given by multiplying the length and width of the rectangle. In this case, the length is 10 and the width is 3x + 5. So, the expression in simplified form for the area of the rectangle is:

Area = 10 * (3x + 5) = 30x + 50
