1. the perimeter is 144 mm. The length of one side of the square is what?

2. the are is 756ft and the base is 28 ft. find the height.

3.an electrician cuts 17ft piece of wire into two pieces. one piece is 9ft longer than the other. How long are the pieces?

4. if a number added to twice the number, the result is -18. What is the number?

5.Find the area of the parallelogram with a height of 2ft and base of 8ft.

P = 144 mm

P of a square = 4 * side

144 = 4 * side

side = 144/4

side = 36 mm

-------------------------------------------------------------------

2)
A = 756 ft^2
Base = 28 ft

Area of triangle = 1/2 * base * ht

756 = 1/2 * 28 * h

h = 756/14

h = 54 ft

-----------------------------------------------------------------

3)
Let the two pieces be x and x + 9

We have :
x + x + 9 = 17
2x + 9 = 17
2x = 8
x = 4

So, first piece is : 4
Second piece : 4+9 = 13

So, two pieces are 4 ft and 13 ft

---------------------------------------------------------------------

4)
Number = x
Twice the number = 2x

x + 2x = -18

3x = -18
x = -6

----------------------------------------------------------------------

5)
Area of parallelogram = b * h

A = 2 * 8

A = 16 square feet
