Answer:
25
y²
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
A = (5x²y)²
= 5 × 5 × x² × x² × y × y
= 25y²
Answer:
Width is 25 ft
length is 60 ft
Step-by-step explanation:
Here, we want to calculate the length and width of the garden
From the question, we are told that the length is 10 ft more than twice its width
So if the width is x ft
Length = 2x + 10
Mathematically, the perimeter of a rectangle i s 2(l + b)
So;
2(x + 2x + 10) = 170
2(3x + 10) = 170
3x + 10 = 85
3x = 85-10
3x = 75
x = 75/3
x = 25 ft
length is;
2(25) + 10 = 50 + 10 = 60 ft
Answer: 9.5
Step-by-step explanation:
Since a sqaure has all 4 equal sides, you can divide the square by 4 since there are 4 sides and it will be equal.
38 ÷ 4 = 9.5
Therefore, the length of each side will be 9.5. Hope this helps!
