The width would be 9 inches. Here's how I got the answer:
Double 12
Subtract from total
Take your difference and divide by two.
That will give you the width.
Answer:
√95 cm
Step-by-step explanation:
To solve, you need to use the pythagorean theorem, or a^2 + b^2 = c^2
The hypotenuse is the c and let one leg be b. You can write:
a^2 + 7^2 = 12^2
a^2 + 49 = 144
Now, you need to solve for a:
a^2 = 144 - 49
a^2 = 95
a = √95 cm, or about 9.75cm
Now subtract, then add.
4 - 2 = 2 then add 12.
2 + 12 = 14.
Answer is 14.
