The length is 9 feet.
The formula for Area is A= L*W*H.
You are given A=189, W= 7 feet and H= 3 feet. Solve formula for
L.
189= L*7* 3
189=21 L
Divide both sides by 21 to solve for L
189/21 = 21L/21
9=L

Please help me im about to fail!!!! Express your answer in scientific notation.
Illusion [34]

Answer:

3.74 x 10^5

Step-by-step explanation:

First expand the term in scientific notation into normal notation.

3.3 x 10^5   -   Here the ^5 tells us to move the decimal five places to the right, so we go from

3.30000 to

330000.00

So 3.3 x 10^5 = 330,000

Now add that to 44,000 and you get 374,000.

Return this number to scientific notation.  Move the decimal back to its spot before the 3.  We go from

374,000.00 to

3.74000

Once again the decimal has moved five places, so that is the number in the exponent of the our scientific notation, and therefore our answer is

3.74 x 10^5

4-62. Find the area and perimeter of the<br> below shape.<br> 7.6 ft<br> 3 ft<br> 7 ft<br> 7 ft
stepladder [879]

Answer:

area= 59.5    perimeter=31.6

Step-by-step explanation:

the area of the square is 49 because 7x7=49 and the area of the triangle is 3x7/2 because it is half of a rectangle so it is 10.5 + 49 = 59.5 and perimeter you add all the sides so 3+7.6+7+7+7= 31.6
