Write an expression using halving and doubling strategy to find 28x50

1400

Step-by-step explanation:

Example:  Halve 28 and double 50, obtaining 14 and 100; then mult. 14 and 100 to obtain 1400 (answer)

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

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
