A number x rounded to 1 decimal place is 3.7
write down the error interval for x

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

i think the length is 12 and the width is 17

i think this is a open ended question but i agree with other guy who said you should ask it at english section
