If the legs of a right triangle are 6 cm and 5 cm find the area of the triangle

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: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
