NEED HELP ! here is a rectangle with a width x centimetres.
the length of the rectangle is 8 cm longer than the width of the rectangle.
four of these rectangles are used to make an 8-sided shape.
the perimeter of the 8-sided shape is 90 cm.
work out the area of the 8 sided shape

step-by-step explanation:

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
