Perimeter questions! Pls help they are kinda hard

I'm not going to do it for you but just offer the way I would do it.

1. Figure the overall area. Multiply the overall width by the overall length to get the overall area. If the overall length is not given, you'll have to add up from the numbers that are given.

2. Figure the area of each cutout. Again, length x width. Again, if they are not given, you'll have to do a little math with what you are given.

3. Subtract the area of each cutout from the overall area.

Step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
