Ok so for the first one it’s super simple I’m gonna do it as less complicated so it can help you :)

So first we need to convert the mixed number to an improper fraction

1 4/5 = 9/5

Now we need to reduce the numbers greatest common divisor which is 3

3/5 x 6

Now multiply the numbers

Your answer is 18/5 I hoped this help

Now for the second one

this one is a little more complicated and I don’t know how to make it sound easier so I’m gonna tell you the answer which is 580/21

The last one is the same steps we did for the first one which is 27/20

I hoped this helped you it is a little difficult but you’ll get the hang of it :)

PLEASE HELP ASAP DUE IN 3 MINUTES

Inga [223]

Answer:

1728 in²

Step-by-step explanation:

For the area of B, you need to find the length and width (height and base, whatever you want to call it).

For the height, you would need to do: 144 - 36 - 24 - 36 = 48 inches

For the base, you would need to do: 60 - 24 = 36 inches

Now you multiply the base and height to get the area: 48 x 36 = 1728 in²
