<u>Answer:</u>
8 meters or 4 meters
<u>Step-by-step explanation:</u>
We know that for finding the area of a rhombus, there are two diagonal sides: one of which is 12.5 meters in length and the other one we'll assume to be y.
Then, we can write:
Area of rhombus =


meters
If the sides of the rhombus are not internally diagonal, then we can simply use the following formula:
Area of rhombus = altitude * side

meters
Answer: 3x + 15 = 51
x is the number of laps that she swims on Monday, Wednesday, and Friday. Since she swims the same amount, we can multiply x by three. Since Saturday gives us an explicit answer, we can just add that to the equation.
Hope this helps :)
I wrote the steps down, hopefully you understand them and the answer is on the lower right corner.
Answer:
104 miles
Step-by-step explanation:
52/2.5 = 20.8
20.8 miles = 1 inch
20.8 x 5
104 miles = 5 inches
the answer would be 80,because 800 divided 10 is 80.
