Answer:
88
Step-by-step explanation:
Basically you look at the number after the decimal point and if it is below 5 it will turn to 88. If it is over 5 it will be a 89. For this you also ignore the 7. The 7 does not mean anything.
That is the simplest form
To work out do the inverse
253+326
579
Then check it by doing 579-326
=253
Y=579
This is a square, and so all the sides will be the same measurements. Note that you are given an area, so you'll have to root the total area to get a side.
√400 = 20
One side's measurements is 20 in
