Question

What is the cost of 0.4 of 174240 square feet of land is the price per acre is 1500

Answer 1

keeping in mind that an acre has 4840 yd², and therefore it has 43560 ft², then how many acres are there in 174240 ft²?


`\bf \begin{array}{ccll} ft^2&acres\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 43560&1\\ 174240&a \end{array}\implies \cfrac{43560}{174240}=\cfrac{1}{a}\implies a=\cfrac{174240\cdot 1}{43560}\implies a=4`

so 174240 is 4 acres, what is the price of 0.4 of 4 acres, if each acre is 1500?

well, the price for all 4 acres will be 1500*4.

what is 0.4 of that? well, is just the product of 0.4 * (1500 * 4).
