the dimensions of rectangle b are twice the dimensions of rectangle a. the area of rectangle a is 50 cm2. what is the area of rectangle b?

Step-by-step explanation:

To double the dimensions, you must multiply both the length and width by 2, so instead of just , you have , which can be simplified even further to

Now, multiply the 2s together to get 4, making the equation . Since is , and is 4 times as much as , you just need to multiply the original area by 4 to get the new area.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

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
