Answer:
Step-by-step explanation:
Let's look at some other ratios that equal 8:6 We could increase them or decrease them. For instance if we cut one in half we cut the other one in half, so 8:6 would be the same ratio as 4:3. With the same thinking if we double one we double the other so 8:6 s the same ratio as 16:12. Now, we want to go from 8 to 28. What do we multiply 8 by to get to it? Or, it might be easier to use 4:3 and see what you multiply 4 by. Then you multiply 3 by that same number to get the other number.
Let me know if that doesn't make sense.
Area of a rectangle = length x height
Area = 135
Height = X
Lenght = x +6
135 = x * x+6
Simplify:
135 = x^2 +6x
Subtract 135 from both sides:
x^2 + 6x - 135 = 0
Solve:
2 numbers when added need to equal 6 and when multiplied equal -135
x = 9 and x = -15
The height can't be a negative number so the height is 9
Length = 9 +6 = 15
Height = 9cm, Length = 15 cm
