To Calculate the cost of <span>The cost of fertilizing, we need to Calculate first the Area of the Triangle.
</span>the Area of the Triangle = 1/2 x base x altitude = 1/2 x (14+√17) x 68 = 524.08 <span>square foot
</span>The cost of fertilizing = the cost of the square foot x the total area = 0.25x524.08 = 131 <span>$</span>
Yes
Divide it by sixty and multiply
I hope this helps
