Answer:
The answer to the question is C
Answer:
Step-by-step explanation:
Perimeter is when you add all the sides together...but oh, no! There are two sides missing! So we have to find it. The horizontal like could be x and the vertical, the y. x would be 3 because one side is 7 and the other side is 4, so if we subtract them, we get 3. Same for the vertical, the y would be 3. (3+3=6)
Now we could add all sides to get the last choice, or 26 cm.
Answer is 28 units because it’s 15 over 42 is equal to 10 over “x”, then you cross multiple which you end up with 15x=420 divide 420 from 15 which equals 28.
