The length of a rectangle is 12 cm.
What is the width if the area is 72 cm?

Width of the rectangle = 6cm

Step-by-step explanation:

Let width be b

Area of rectangle = 72cm²

length× width = 72cm²

12×b= 72

b= 72/12

b= 6cm

Width = 6 cm.

Step-by-step explanation:

The formula for are is length x width. You have the length, which is 12. This gives you this equation...

12 x ? = 72 cm.

If you use the inverse operation (opposite) of multiplication, you divide both sides by 12, giving you 6 cm. To double check, do 6 x 12, which equals 72.

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
