<span><span>Mary is saving up money to go on a trip. This month, she saved three times as muchmoney as she saved last month. Last month, she saved $24.00. How much money did Mary save this month?</span><span>As much as tells you that you have a comparison.Three times is the multiplier.$24.00 is the amount in the first set.How much money did Mary save this month? is the question you are being asked. To solve, multiply $24.00 x 3.
</span><span>$24.00 x 3 = $72.00.It’s important to clearly show that you understand what your answer means. Instead of just writing $72.00, write:Mary saved $72.00 this month.</span><span>Whenever you finish a math problem of any kind, always go back to the original problem. Think: “What is the question I am being asked?” Make sure that your final answer is a reasonable answer for the question you are being asked.I was asked, “How much money did Mary save this month?” My answer is:<span> Mary saved $72.00 this month.</span>My answer is reasonable because it tells how much money Mary saved this month. I multiplied a whole number by a whole number, so the amount of money Mary saved this month should be more than she saved last month. Seventy-Two is more than 24 . My answer makes sense.</span></span>

Since we know that we can find area of a trapezoid by dividing our trapezoid into two triangles with parallel sides of trapezoid as bases of our triangles. The area of trapezoid is sum of the areas of these two triangles.
We have been given that areas of our triangles are and . We can find area of our trapezoid by adding areas of our both triangles.
Therefore, area of our trapezoid will be .
