the sides of the rectangular field are in the ratio 9:7 and the perimeter is 144 meter. Find the sides.
length --- 9x
width ---- 7x
2(9x) + 2(7x) = 144
solve for x, sub back into my definitions
2(9x)+2(7x)=144

To find the sides of the rectangular field, we need to use the information given.
Let's assume that the sides of the rectangular field are 9x and 7x, where x is a common factor.
The perimeter of a rectangle can be calculated by adding the lengths of all four sides.
Given that the perimeter is 144 meters, we can set up the following equation:
2(9x) + 2(7x) = 144
Simplifying the equation:
18x + 14x = 144
32x = 144
Dividing both sides of the equation by 32:
x = 144/32
x = 4.5
Now we know that x is equal to 4.5. We can substitute this value back into the equation to find the lengths of the sides:
Length = 9x = 9 * 4.5 = 40.5 meters
Width = 7x = 7 * 4.5 = 31.5 meters
Therefore, the sides of the rectangular field are 40.5 meters and 31.5 meters.
