The length of a rectangle is two more than its width. find the perimeter of this rectangle if its area is 15 ft.²

Perimeter = 16ft

Step-by-step explanation:

Let the width(w) of the rectangle be x ft

The length(l) of the rectangle will be (x + 2) ft

Area of the rectangle is 15ft²

Area of a rectangle = l × w

(x + 2)x = 15

x² + 2x - 15 = 0

Applying the quadratic formula;

x = (-b ± ) ÷ 2a

x = (-2 ± ) ÷ 2

x = 3 or -5

Since the width can't be negative, we take 3ft to be the value of our width

The length is therefore 3ft + 2ft = 5ft

Perimeter(p) = 2l + 2w

p = 2(5) + 2(3) = 16ft

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
