can someone please help? If you could Atleast explain question 1 and 4 that would help. but preferably ig someone could awnser and explain all the questions

Answer:
1)7*3
4)m^2
Step-by-step explanation:
The first four problems deal with the area of the rectangle, or length times width(7*3,m*m=m^2).
The last four problems are dealing with adding areas. Find the area of the two rectangles(length times width), then add them together to find the total area.
Answer:
Area = Base • Height
1) 3 • 7
2) 4 • a
3) [tex]m^{2}[/tex]
4) 4(x + 1) = 4x + 4
5) 7(d + 4) = 7d + 28
6) y(y + 3) = [tex]y^{2}[/tex] + 3y
Step-by-step explanation:
They are asking for an expression. An expression is made up of terms, variables, and an operation. They do not contain equal signs.
For questions 4 through 6, they want you to use the distributive property. There is no way of solving them without having either the length of both sides or the total area.
