Answer:
$652.5
Step-by-step explanation:
The interest earned in one year would be $130.50 because 1450*.09= 130.50
so then the interest for 5 years would be 652.5 because 130.5*5=652.5
Answer:
<em>A = 250 square ft</em>
Step-by-step explanation:
<u>Equations</u>
Let's call:
x = width of the game room
The length is 5 more than twice the width, thus:
2x+5 = length of the game room
The perimeter of a rectangle is twice the sum of the width and the length:
P = 2( x + 2x + 5 )
And the perimeter is 70 ft:
2( x + 2x + 5 ) = 70
Operating:
2( 3x + 5 ) = 70
Dividing by 2:
3x + 5 = 35
Subtracting 5:
3x = 30
Dividing by 3:
x = 30 / 3
x = 10
The width is 10 ft and the length is 2(10)+5=25 ft
The area of the game room is:
A = 10 ft * 25 ft
A = 250 square ft
