Answer:
Width: 90m
Length: 120m
Step-by-step explanation:
Width = 3/4x
Length = x
2(3/4x) + 2x = 420m
6/4 x + 2x = 420m. (6/4 + 2 = 7/2)
7/2x = 420m
7x = (420)*(2)
x = 840/7 = 120
Width = (120)*(3/4) = 90
Length: 120
2(90)+2(120)= 420m
Substituting -3 for x, we have: (-3)^2-3*-3-7. This simplifies to 9+9-7, or 11.
Answer:
one side would be 90.25 if its a squared garden and the total area is 361. that would mean 361/4 because 4 sides and one side would be 90.25.
I can help with the second part of your question. The first part is missing something.
To find the amount of interest, just multiply the amount by the given percent.
200 x 0.03 = 6
150 x 0.03 = 4.5
6 - 4.5 = 1.5 is the additional amount of interest.
