The length of a rectangle is one foot more than twice it’s width. if the area of the rectangle is 300 ft.² find the dimensions of the rectangle

Length= 12  ft

Width= 25 ft

Step-by-step explanation:

We will use the area of the rectangle formula to solve this question. The formula is:

Let, the width of the rectangle is x, so the length is one foot more than twice it’s width, and is written as:  

width= 2x+1

Now the area of the rectangle is given as:

300

So using the formula of the area of a rectangle, we get:

But we will take only positive value of x, as length can't be negative.

So the dimensions of the rectangle are:

Length= 12  ft

Width= 25 ft

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
