Answer:
perimeter- 36 in.
area- 77
Step-by-step explanation:
to find the perimeter you add all of the sides, so
7 + 7 + 11 + 11 = 36
*** the opposite side of the 7 is also 7, same with the 11 :)
to find the area for a rectangle, you use the formula A=b*h
so, the base(b)=7 and the height(h)= 11
therefore, 7 * 11 = 77

Answer:
y = 1.5
Step-by-step explanation:
Given x is inversely proportional to , then the equation relating them is
y = ← k is the constant of proportion
To find k use the condition when x = 8, y = 2
2 = =
=
( multiply both sides by 3 )
6 = k
y = ← equation of proportion
When x = 15 , then
y = =
=
=
= 1.5
