Answer: 15 cm²
Step-by-step explanation: To find the area of a triangle, start with the formula for the area of a triangle which is shown below.

In this triangle, the base is 6 centimeters and the height is 5 centimeters. Now, plugging into the formula, we have
.
Now, it doesn't matter which order we multiply.
So we can begin by multiplying 1/2 times 6 cm and notice that the 2 in 1/2 and the 6 cross cancel to 1 and 3. So we're left with 3 cm.
Now, (3 cm)(5cm) is 15 cm².
So the area of the triangle is 15 cm².
Answer:
3 /5
Step-by-step explanation:
Given that:
Ratio of red to green to tiles = 2:3
Red = 2
Green = 3
Total sum of each part (red + green) = (2 + 3) = 5
Fraction of green tiles :

3 / 5
Answer:
1. -370
2. 70
3. 10.75
4. 6700
5. 37.26
Step-by-step explanation:
1. Estimating the solution means round the numbers to the nearest ten, then subtract the rounded numbers.
2. Same thing as #1
3. Using long division, it should be quite easy. If you need more evaluation, comment and I'll answer.
4. To the nearest hundred, you write the closest exact hundred. example: 8334 would be rounded to 8300.
5. To the nearest hundredth, you write the closest exact hundredth. example: 65.734 would be rounded to 65.73
Hope this helped, good luck!
