Answer:
Total area = 12x^2 + 2x
Perimeter = 18x+4
Step-by-step explanation:
Divide the figure into two separate shapes to make the question easier.
Area = lw
Area (bigger shape) = (3x)(3x)
Area (bigger shape) = 9x^2
Area = lw
Area (smaller shape) = (3x+2)(x)
Area (smaller shape) = 3x^2+2x
Add the areas of the bigger and smaller shapes to get the total area:
Total area = 9x^2 + 3x^2 + 2x
Total area = 12x^2 + 2x
To find the perimeter, add the lengths of all the sides.
(3x)+(3x)+(3x)+(3x)+(3x+2)+(3x+2)
(12x)+(6x+4)
perimeter = 18x+4
Answer:
6a+2
Step-by-step explanation:
remove parathese
4a+ (2a+2)
4a+2a+2
Then do 4a + 2a which is 6a
You will then get 6a + 2
Hopefully this helped!
