问题 Mandy has a garden that is shaped like a right triangle, as shown below.
[br] A bag of fertilizer costs $8.25 and will cover approximately 300 square feet. Which of the following is closest to the cost, in dollars, of fertilizing the original garden?
选项 A、$20.00
B、$25.00
C、30
D、40
E、50
答案 B
解析 The correct answer is B. To solve this problem, first calculate the total area. Recall that the formula for the area of a triangle is(b)(h). Therefore, the area to be covered by the fertilizer is(48)(36)= 864 square feet. Next, determine the number of bags of fertilizer needed: 864 ÷ 300 = 2.88. Mandy will need at least 3 full bags of fertilizer, so she will spend $8.25 × 3 = $24.75, or about $25 on fertilizer for her garden.
