Answer:
See below ~
Step-by-step explanation:
Finding the distance of each side length :
- AB = √(3 - 0)² + (0 - 4)² = √9 + 16 = √25 = 5
- BC = √(7 - 3)² + (3 - 0)² = √16 + 9 = 5
- CD = √(4 - 7)² + (7 - 3)² = √9 + 16 = 5
- DA = √(4 - 0)² + (7 - 4)² = √16 + 9 = 5
- All sides are equal
- Hence, it is a square
Perimeter :
- 4 x side length
- 4 x 5
- 20 units
Area :
- (side length)²
- (5)²
- 25 square units
17. You are supposed to use the perimeter formula for a rectangle. Your text has apparently written that formula as
.. P = 2w +2l
You are given values for P and l. Put them in the formula.
.. 6 = 2w +2*1
Solve in the usual way. First, subtract 2.
.. 4 = 2w
Then, divide by 2
.. 2 = w
You have found w, and it is 2.

Personally, I like to write the perimeter formula for a rectangle as
.. P = 2(w +l)
Usng this version, we can fill in values and get
.. 6 = 2(w +1)
Dividing by 2 gives
.. 3 = w +1
Subtracting 1, we get
.. 2 = w
Answer:
0.4 meter
Step-by-step explanation:
24/3=8
3.2/8=0.4
Answer:
7
Step-by-step explanation:
That would be 6 4/9 plus 5/9. Note that 4/9 + 5/9 = 9/9 = 1.
Therefore, 6 4/9 plus 5/9 = 6 4/9 + 5/9 = 6 9/9 = 7
