The length = 6W + 7. 2L + 2W = 70. This is a system of equations. To get L by itself in the second problem, -2W from both sides to get 2L = 70 - 2W. Divide by 2 to get L = 35 - W. Now put them together. 6W +7 = 35 - W. Add W to both sides to get 7W + 7 = 35. Subtract 7 from both sides to get 7W = 28. Divide 7 to both sides to get W = 4. Now replace W with 4. 6(4) + 7 = L. 24 + 7 = 31. The length is 31. To check, do the second equation. 2(31) + 2(4) = 62 + 8 = 70. Your answer is 31.

Answer:
It says that for me too, there must be a problem with their system.
Try asking the specific problem you are having, so if someone had that specific problem before, they can walk you through it! :)
Answer:
<h2>
93.4 m</h2>
Solution,
Area of rectangle = 159.1 m^2
Length of rectangle = 3.7 m
Breadth of rectangle = ?
perimeter of rectangle = ?
Now,
Area of rectangle = 159.1 m^2
or, length * breadth = 159.1
or, 3.7 * breadth = 159.1
or, 3.7 breadth = 159.1
or, breadth = 159.1 / 3.7
breadth = 43 m
Again,
Finding the perimeter of rectangle:
perimeter of rectangle:
= 2 ( length + breadth)
= 2 ( 3.7 + 43 )
= 2 * 46.7
= 93.4 m
Hope this helps...
Good luck on your assignment...
