The length of a rectangle is 3 more inches than its width. the area of
the rectangle is 54 square inches. what is the width of the rectangle
in inches?

9

Step-by-step explanation:

Length: a

Width: b

ab = 54

a = b + 3

=> (b + 3)b = 54

=> b^2 + 3b = 54

=> b^2 + 3b - 54= 0

=> (b - 6)(b + 9)

=> b = 6 AND b = -9

Rectangular's sides > 0 => b = 6

Hope it's helpful :)

step-by-step explanation:

their are no angles. sorry cant .

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
