Final answer:
The length of the height of the rectangle is 3.8 meters or the mixed number 3 4/5 meters.
Step-by-step explanation:
To find the length of the height of the rectangle, we can use the formula for the area of a rectangle:
Area = length × width
Given that the area is 4.75 m² and the length of the base is 1 1/4 meters, we can plug in these values to the formula:
4.75 = (1 1/4) × height
To solve for the height, we need to isolate the height on one side of the equation:
Dividing both sides of the equation by 1 1/4, we get:
height = 4.75 ÷ (1 1/4)
Simplifying the division, we have:
height = 3.8
So, the length of the height is 3.8 meters or the mixed number 3 4/5 meters.
