Astudio-type room has a length that is twice its width. the rooms can be sold for p750 per
square meter. write the function of its area and determine the cost of the room if the width is 4
meters.​

a = l x w

a / l = (l x w) / l

a / l = w

w = a / l = 108 / 12

w = 9 inches

next , the one inch border reduces the length and the width each by 2 inches, so l and w now equal 10 and 7

a = l x w = 10 x 7 = 70 sq inches left for painting

i'm not sure

answer: -11x + 6y-41

step-by-step explanation:

if you're figuring it just need to find what to add to get the numbers

to get a -6, you need to add -11 to 5

to get 6y, you just need to bring that and to remove 41, you need to subtract to itself to make it 0

so you have -11x +6y -41
