Answer:

Step-by-step explanation:
We know that the length is four times the width, so:

We also know the area, which is 324 m². The formula for area:

Insert the known values:

Solve for w. Simplify by removing parentheses:

Divide 4 from both sides to isolate the variable:

Find the square root of both sides:

The width is 9 m.
We know the width. Now find the length by using the area formula and inserting known values:

Solve for l. Divide both sides by 9:

The length of the rectangle is 36. (You can check: 4 times 9 is 36)
Now find the perimeter:

Insert values:

The perimeter is 90 m.
Answer:
The correct option is (c).
Step-by-step explanation:
The given expression is :

We need to use the associative property to make it easier.
The associative property for multiplication is as follows :

We have,


Hence, the correct option is (c).

Step-by-step explanation:
The point A(2, 4) is
rotated 270 ccw, so the A' should be on the 4th quadrant
=> A' (4, -2)
Answer:34
Step-by-step explanation:
First you multiply
-7•-3=21
Then you just add 9+4+21
9+4=13
21+13=34
