and width 4 units.
wa

The perimeter of the given rectangle  = 20 units.

Step-by-step explanation:

Length of the rectangle =  6 units

The width of the rectangle = 4 units

Now Perimeter of the Rectangle  = 2 ( LENGTH + WIDTH)

⇒Here, perimeter  = 2 ( 6 units + 4 units ) =  2 x ( 10 units)

                                 = 20 units

Hence, the perimeter of the given rectangle  = 20 units.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
