A×4 = E, so A = E/4
B/4 = E, so B = 4E
C+4 = E, so C = E=4
D-4 = E, so D = E+4
and
A+B+C+D=100.
now substitute the values that we got of A, B, C and D in the equation, to get,
(E/4) + 4E + E-4 + E+4 = 100
(E/4) + 4E + 2E = 100
(E/4) + 6E = 100
(E+24E)/4 = 100
E+24E = 100×4
25E = 400
E = 400/25
E = 16

The length of rectangle is 45 inches and width is 5 inches.
Step-by-step explanation:
Given,
Perimeter = 100 inches
The ratio of length and width = 9:1
It means that 9 times of any number and 1 times of any number will be the original length, therefore,
Let,
x be the that number.
Length = 9x
Width = 1x
Perimeter = 2(Length+width)

Dividing both sides by 20

Length = 9x = 9*5 = 45 inches
Width = x = 5 inches
The length of rectangle is 45 inches and width is 5 inches.

if two opposite sides are 4cm each then their total length is 8cm. If the total length is 24cm then to work out the possible lengths of the other two sides you subtract 8 from 24 which gives you 16. A rule in rectangles is that opposite sides are equal so each remaining side would have a length of 16/2 which is 8. To get all the possible answers you have to go through all the possible perimeters (assuming all perimeters have to be whole numbers) between 24(max) and 9(min) and do those steps.
Answer:
im sorry i dont know
Step-by-step explanation:
<span>ratio 5:7
so 5 + 7 = 12
360 /12 = 30
5 x 30 = 150
7 x 30 = 210
answer
</span><span>360 in the ratio 5:7 = 150:210</span>
