1. 15*13=195
2. 7*13=91/2=45.5
3. 7*13=91/2=45.5
4. 195+45.5+45.5=286 units squared
hope this helps!
Answer:
Length: 20 or 40 feet
Width: 40 or 20 feet
Step-by-step explanation:
Area = 800 = length*width = x*(60-x)= 60x - x^2
- x^2 + 60x - 800 = 0
x = 20
Or x = 40
So length can be either 20 feet or 40 feet and width can be 40 (60-20) or 20 (60-40)
Note: This is a perfect application for equations of ratios.
50 40
------- = ------- and so 50x = 1200, or 5x = 120, or x = 24 (miles).
30 x
With what you've jus given me, no. is there an equation or something to go along with this question?
