The length of a rectangle is three less than two times the width. if the perimeter is 60, what is the length?

19 units.

Step-by-step explanation:

Let the width be x units

The length will be 2x - 3 units

The perimeter is 60 units;

Perimeter is given by 2(width) + 2(length)

2(x) + 2(2x - 3) = 60

2x + 4x - 6 = 60

6x = 66

Dividing through gives;

x = 11 units

So the width is 11 units;

The length is 2(11) - 3 = 22 - 3 = 19 units

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer is c)8
