Answer:
4096 cm²
Step-by-step explanation:
Perimeter of a square is given by the formula :
P = 4a
Now we substitute P To solve for a :
256 = 4a
a = 256÷4
a = 64
Area of a square is given by the formula :
A = a²
Now we substitute the value of a worked out from perimeter to work out the area :
A = 64²
A = 64×64
A = 4096
Units will be cm² as it is area
Hope this helped and have a good day
Answer:110
Step-by-step explanation:
its right i know
Step-by-step explanation:
what we trying to find the value of x and y
20x+6=y
x intercept,y=0
20x+6=0-6
20x/20=-6/20
×=-0.3
y intercept,x=0
20(0)+6=y
0+6=y
6=y
(-0.3,0)
19x+7=y
y intercept,x =0
19(0)+7=y
0+7=y
7=y
x intercept,y=0
19x+7=0-7
19x=-7
19x/19=-7/19
x=-0.37

Answer:
4.5 ounces
Step-by-step explanation:
First dived 3 by 2 to figure out how much water she drinks in 1/3 of a hour.
Second, you take the answer 1.5 ounces per 13 of an hour and multiply it by 3.
Lastly, you get your answer 4.5 ounces of water in a hour.
1. 3 / 2 = 1.5
2. 1.5 x 3 = 4.5
