Answer:
length of a rectangle is 5 more than twice the length. I believe
you mean the length of a rectangle is 5 more than twice the
width.
From the information given we can make two equations,
thus forming a system to solve. We know the perimeter
of a rectangle is 2(length + width) and area = length*width.
length of a rectangle is 5 more then twice the width:
L = 2w + 5
The perimeter is 130:
2(L+w) = 130
L+w = 65
Since we know L=2w+5 we can substitute that into 2nd equation
to solve for w
2w + 5 + w = 65
3w = 60
w = 20
L = 2w+5 = 45
The area is length*width = 20(45) = 900 square units
The surface to be paint is 4 * 12*8.5= 408 ft squared
1 gallon.......75 ftsquared
x gallon.......408 ft squared
------------------------------------
x= 408/75= 5,44 gallons

Answer:
Sam will get £30 while Bethan will get £24.
Step-by-step explanation:
The total ratio shared by Sam and Bethan is 5+4 = 9
1 share ratio is the total amount involved divided by the total ratio
That is, £54/9 = £6
if 1 share ratio is £6,
Sam with 5 share ratio will get £6*5 = £30
while Bethan with ratio 4 wiill get £6*4 = £24
