10 m / sec = 10/1000 = 1/100 km/sec
there are 3600 seconds in an hour
so his speed in km / hr = 1/100 * 3600 = 36 answer

First find the area of the triangle.

$\sf A=\dfrac{1}{2}bh$

$\sf A=\dfrac{1}{2}(6)(12)$

$\sf A=36cm^2$

ABCE is a parallelogram, this means that the area of triangle ABE is equal to the area of triangle EBC. The are of the entire trapezoid is 180 square centimeters, we already found the area of the triangle, so that leaves us with:

$\sf 180-36=144$

So the area of the entire parallelogram must be 144 square centimeters. So each half of the parallelogram must be equal to:

$\sf 144\div 2=\boxed{\sf 72cm^2}$

I forgot how to multiply by division and multiplication. It’s been such a long time since I’ve done it i’ve practically forgot h

Answer:

First, multiplication:

Multiplication is repeated addition, there's really no way to put it simpler. For example:

4 × 6 = 24 because 4 + 4 + 4 + 4 + 4 + 4 = 24

3 × 3 = 9 because 3 + 3 + 3 = 9

9 × 2 = 18 because 9 + 9 = 18

Multiplication, like addition, can also work backwards, so 6 × 4 is also 24, 2 × 9 is 18, and so on.

I recommend practicing your times tables up to 12 if your remembrance has gotten really bad.

Now division:

Division has the same properties as multiplication, except with subtraction. The difference, however, is that division does not work backwards. It's the same as subtraction.

Here are some examples for division:

6 ÷ 3 = 2 because 6 - 3 - 3 = 0 (3 can be subtracted twice, so the answer is 2)

12 ÷ 4 = 3 because 12 - 4 - 4 - 4 = 0

20 ÷ 2 = 10 because 20 - 2 - 2 - 2 - 2 - 2 - 2 - 2 - 2 - 2 - 2 = 0

I'd recommend practicing your long division if you are struggling.

Hope this helped you! If you have any more questions, send me a friend request and I'll check for more questions every so often. :)
