a) find area
a = l • w
a = 17.8 • 10.6
a = 188.68 m²
//
b) find the area of the vegetable garden and then multiply by the cost
a = l • w
a = 49 • 15.2
a = 744.8 m²
total cost = 744.8 • 91
total cost = 67776.8
//
c) find perimeter
p = 2(l) + 2(w)
p = 2(18.7) + 2(12.6)
p = 62.6 m
//
d) find area then divide by 1.25
a = l • w
a = 20 • 15.7
a = 314 m²
314/1.25 = 251.2
251.2 banana trees
//
Just double check to make sure my calculations are correct.
