Answer:

15x^2+35x

Explanation:

As the area formula is L*W, you're essentially doing the same thing here by multiplying both of these sides to get your area expression.

Take 5x and use the distributive property to multiply it with 3x+7 to get 15x^2+35x.

Answer:

A = 5x · (3x + 7)

= 5x(3x) + 5x(7)

= 15x² + 35x meters
