Answer

Yes, it is enough to cover the lawn

Work Step by Step

We need to find the area of the triangle, which can be found by using the formula: A = $\frac{b\ \times\ h}{2}$ Substitute 130 for b and 60 for h to obtain: A = $\frac{130\ \times\ 60}{2}$ A = 130 $\times$ 30 A = 3900 square feet Since one bag of fertilizer covers 4000 square feet, it is enough to cover the lawn, which is 3900 square feet.
