xxTIMURxx [149]

Answer:

Part a) The length of the rectangle is 12\ ft

Part b) The area of rectangle is 72\ ft^{2}

Step-by-step explanation:

step 1

Find the length

Let

L-----> the length of the rectangle

W---> the width of the rectangle

we know that

The perimeter of rectangle is

P=2(L+W)

P=36\ ft

so

36=2(L+W)

18=(L+W) ----> equation A

L=2W -----> equation B

substitute equation B in equation A

18=(2W+W)

solve for W

18=3W

W=18/3=6\ ft

Find the value of L

L=2(6)=12\ ft

step 2

Find the area

The area of rectangle is equal to

A=LW

substitute the values

A=(12)(6)=72\ ft^{2}

You deposit $300 in a savings account. The account earns 2% simple interest per year.
Sholpan [36]

Answer:

Answer:

a. ----> $10

b. ----> $110

Step-by-step explanation:

Step-by-step explanation:

principle ( p ) = $100

time ( t ) = 10 years

rate ( r ) = 11%

simple interest = (p × r × t)÷ 100

= ( $100 × 11 × 10 )÷ 100

= 11000 ÷ 100

= $110

interest = simple interest - principle

interest = $110 - $100

= $10
