Answer:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.
Answer:
width is 12 and length is 16
Answer:
y = 5x + 18.......[1]
y = -6x - 15......[2]
equating equation 1&2 we get
5x+18=-6x-15
5x+6x=-15-18
11x=-33
x=-33/11=-3
x=-3
again
y=5×-3+18=-15+18=3
so,x=-3,y=3
77 feet^2
Explanation:
Area of the wall is
8 2/5 × 18 1/3
42/5 × 55/3
14/5 × 55/1
14/1 × 11/1 = 154 feet^2
The area we want is half of this
77 feet^2
Hope this helps and answer you question
