Answer:
9 =z
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w) where l is the length and w is the width
P = 2(3z+2+ 4z)
Combine like terms
P = 2(7z+2)
Substitute in the perimeter
130 = 2( 7z+2)
Divide each side by 2
130/2 = 2/2 ( 7z+2)
65 = 7z+2
Subtract 2 from each side
65-2 = 7z+2-2
63 = 7z
Divide by 7
63/7 = 7z/7
9 =z
Answer:
B. 102 cm
Step-by-step explanation:
The first step would be to find the area of the whole figure and subtract the white area off.
So, to do that simply multiply the length x width to get the area of the whole figure.
20 x 6 = 120(area of the whole figure)
Next, 20-11 = 9 is the length of the figure and because the square has a side length of 3, the other side would also have to be 3.
3 x 3 = 9(area of the smaller square.
9-3=6
6-3=3
Area of triangle = Base x Height Divided by 2.
So, 3x6=18/2=9
9+9=18
Finally, subtract 18(total area of white smaller shapes) from 120 and you will get the final answer
102 cm.
