Answer:
60
Step-by-step explanation:
We can use the pythagorean theorem to find the leg.
10^2+x=13^2
x=12
We now find the area given the height of the triangle.
10 X 12=120
120/2=60
It’s meters squared. Since you need to find the area in order to find the amount of fertilizer, the area is expressed as the unit squared.
Hi there
Replace the blank space by x
so x/7 > 800
All you have to do is cross-multiply
x > 7*800
x> 5600
I hope that's help !
