Answer:
multiple 9 x 1 and add 2....= 11
11/9
Answer:
ok so if we take length to be x we know width is x-3
the perimeter is the total length of sides, if you look at a rectangle you can see it has 4 sides with 2 length and 2 width. so perimeter is 2 times (x + x-3) = 26.
2x -3 = 13, 2x = 16, x = 8, 8 is length
the width is then 8-3 = 5.
Length = 8, width = 5.
The area is 128
multiply the base by the height, and then divide by 2.
the base is 16 and the height is also 16 so 16x16 is 256 divided by 2 is 128
