I think you would do 39 x 4 because if the SQUARE brick has sides 1 foot long, you count up the sides and get 4 feet. She has 29 square feet of patio bricks so you would multiply 39 x 4. I don't know if this is correct. Hopefully I helped!

sorry i dont know, i just rlly need points
Step-by-step explanation:
6hrs = school
9hrs = sleeps = 18hrs // 24hrs ----6hrs left
3hrs = plays
6hrs = other things
playing = 12.5% -- 3/24 3/24*100
other things = 25% -- 6/24 6/24*100
Sum of angle in a triangle is 180, so 33+70+x=180
x=77
x and y are vertical angles so y=77
SA: 2xLxW + 2xWxH + 2xLxH
SA: 2x4.5x20 + 2x4.5x23 + 2x20x23
SA: 180 + 207 + 920
TSA: 1307cm2 (squared)
