Answer:
11 inches by 8.5 inches
Step-by-step explanation:
We can use proportions to solve this problem, drawing on top, real life on bottom
1/2 inch x inches
-------------- = ----------
1 ft 22ft
Using cross products
1/2 * 22 = x*1
11 =x
11 inches
1/2 inch x inches
-------------- = ----------
1 ft 17ft
Using cross products
1/2 * 17 = x*1
8.5 =x
Multiply the denominators to be the same Lowest common multiple. when the denominators are both the same you can add the numerators together
e.g. 3/5 + 2/10
= 6/10 + 2/10
= 8/10
