The height of a floor-standing speaker is five times its width. The perimeter of its front panel is 84 in. Find the height and width of the speaker

divide by 5

step-by-step explanation:

60/5 = 12

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
