Answer:
9m ×5m
Step-by-step explanation:
Area of a rectangle= length ×width
Let the width be W meters and the length be L meters.
2 equations can be written from the given information:
45= WL -----(1)
L= W +4 -----(2)
Substitute (2) into (1):
45= W(W +4)
<em>Expand:</em>
45= W² +4W
<em>-45 on both sides:</em>
W² +4W -45= 0
<em>Factorise:</em>
(W +9)(W -5)= 0
W+9=0 or W-5=0
W= -9 or W= 5
(reject)
Substitute W= 5 into (2):
L= 5 +4
L= 9
∴ The dimensions of the garden is 9m ×5m.

John get money $630 and bill get money $270.
Given that John and bill shared $900 in the ratio 7:3 respectively.
The ratio is defined as the comparison of two quantities of equal units, indicating the quantity of one quantity contained in the other quantity.
The total ratio is 7+3=10
For john:
John has money seven out of 10 for the $900, we get
J=900×(7/10)
J=90×7
J=630
For bill:
Bill is three out of ten for $900, we get
B=900×(3/10)
B=90×3
B=270
Hence, john get money $630 and bill get $270 when they both shared $900 in the ratio 7:3 respectively.
