70-3·6+9
Remember PEMDAS.
You must multiply the 3 and 6 together, and you would get 18.
Then, you subtract 18 from 70, which would give you 52.
And finally, you would add 9 to 52, getting 61 as your final answer.
First you do 3 + 4 + 5 = 12, so there are 12 parts to this ratio.
48 / 12 = 4, this means that each part of the ratio is worth 4 inches.
The longest side is worth 5 parts of the ratio.
4 * 5 = 20 inches
