Answer:
Step-by-step explanation:
Information that we know about the square:
side length: 
which can asol be expressed as: 
we can use this information to calculate the area by the formula for the area of a square:
we subtitute the side length:
the square root and the squared exponent cancel each other out (because they are opposite operations) and since this is an area it must have squared units:
The exact value of the area of the square is 
Thats four questions, but okay :) 1.) 1 16/32 is just an hour and a half, and 1 2/8 is a hour and 15 minutes. that adds up to 2 hours and 3/4 or 2 hours and 45 minutes. 6-2 3/4 =3 1/4 hours, or 3 hours 15 minutes. 2.) convert the 1/3 and 2/5 into 10/30 and 12/30 so they have the same denominator, add them. that equals 22/30. now convert the 9/10 into 27/30 for easy subtraction. 27/30 minus 22/30 is 5/30, simplify that and it is 1/6. so betty needs a 1/6 of a gallon more. 3.) 32 6/12 is just 32 and 1/2. and thats 1/5 of his stuff. so take 32.5 and multiply it by 5, which equals 162.5 minutes. that is 2 hours 42 minutes, and 30 seconds. 4.) take 6 3/8 and multipy that by three for one week. that is 19.125. now multipy that by three since there are three weeks. that equals 57.375 which as a fraction is 57 3/8. so he would run 57 and 3/8 miles in three weeks of training. sorry about my spelling, im ust trying to type fast so you can get this fast. :)

Answer:
<h3>1863 m squared</h3>
Step-by-step explanation:
So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)
So:
12 x 23 = the missing square = 276
31 x 69 = rectangle with the square = 2139
Total area = 2139 - 276 = 1863
Answer:
66
Step-by-step explanation:
11 - 9 + 8^2
11 - 9 + 64
= 66
