As we can see, we are left with 6 equal parts. This can be confirmed by solving the equation:
Answer: 102.4 cm^2
Step-by-step explanation:
find the surface area of all of the rectangles
7.2(4)=28.8
7.2(2)=14.4
7.2(4)=28.8
7.2(2)=14.4
4(2)=8
4(2)=8
add
28.8+14.4+28.8+14.4+8+8=102.4

Answer:
Y = 14
Step-by-step explanation:
1/2(-9 + y) = 2.5
1/2 * -9 = -4.5
1/2 * y = 0.5y
-4.5 + 0.5y = 2.5
+4.5 +4.5
0.5y = 7
/0.5 /0.5
y = 14
