find the area
length: x + 7
width: x + 3
To find the area, we need to multiply the length by the width.
Area = (x + 7) * (x + 3)
Area = x^2 + 7x + 3x + 21
Area = x^2 + 10x + 21
Therefore, the area is x^2 + 10x + 21.
length: x + 7

Area = (x + 7) * (x + 3)
Area = x^2 + 7x + 3x + 21
Area = x^2 + 10x + 21
Therefore, the area is x^2 + 10x + 21.
