The width is 7 meters and the length is 13 meters
Step-by-step explanation:
The perimeter of a rectangle sandpit is 40 meters.
Let the width be w units, then the length which is 1 meter less than twice it’s width becomes: 
The perimeter of a rectangle is given by:

We substitute P=40 and the length in term of w to get:

We simplify to get:

Divide through by 2 to get:
Hence 
find area or centimeters?

Step-by-step explanation:
<u>Problem 9</u>
- h(1/8) = 3(1/8) + 1/4
- h(1/8) = 3/8 + 2/8
- h(1/8) = <u>5/8</u>

<u>Problem 10</u>
- Q(k) = k - 3 / 2
- -4 = k - 3 / 2
- -8 = k - 3
- k = -8 + 3
- k = <u>-5</u>
