A pile of sand has a weight of 90kg

Step-by-step explanation:

Small bag has 2 parts which is 7.5kg*2=15kg

Medium bag has 3 parts which is 7.5kg*3=22.5kg

Large bag has 7 parts which is 7.5kg*7=52.5kg

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
