Collins dining room is 12 feet wide and 26 feet long. colin wants to install wooden trim around the top of the room. the trim costs $2 per foot. how much will it cost colin to buy enough trim?

624

Since it’s 12 feet wide and 26 feet long, we will be finding the AREA. which for a rectangle is: b x h or l x w

12 x 26 = 312

Since one foot costs $2 we will multiply the area by 2 which gives the answer of $624

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
