100-25=75
find 75% of the 85
percent means parts out of 100
75%=75/100=0.75
'of' means multiply
75% of 85 means
0.75 times 85=63.75

Answer:
<h2> 25 centimeters</h2>
Step-by-step explanation:
Ratio 4:5 means:
width: W = 4x
length: L = 5x
Area of rectangle: A = W×L
Therefore:
500 = 4x×5x
500 = 20x²
50 = 2x²
x² = 25
x = 5
W = 4×5 = 20 cm
L = 5×5 = 25 cm
Set the following: Length = L Width = W
The length is twice the width: L = 2*W or: W = L/2
Perimeter: P = 60ft = 2*L + 2*W
Substituting L for W in the perimeter equation gives:
P = 60ft = 2*L + 2*(L/2) = 2*L + L = 3L
L = 60ft/3 = 20ft W=L/2=20ft/2=10ft
Verify result: Perimeter= P = 60ft = 2L + 2W = 2*20ft +2*10ft = 40ft+20ft = 60ft
The area of the rectangular is: Area = A = Length*Width = L*W = 20ft*10ft = 200 (ft)^2

We can simplify 2√5+3√5-√5 because they all have the same radical, √5. Now that we know this, we can imagine that there are no radicals, and that we are just adding numbers. This results in our expression being 2 + 3 - 1. This gives an answer of 4. Finally, we add the √5 to the 4 to get 4√5.
