The perimeter of a rectangle is 354 km. Its side lengths are 81 km, 81 km, and 96 km. The fourth side length is given as "f" km. What is the value of f?

96km

Step-by-step explanation:

Perimeter of a rectangle

Here already the length ( sides ) are provided.

That is 81 km

Now the question is what is the breadth?

In simple words as one of the breadth is 96km so the other one will also be 96 km because 2(l+b) = the perimeter of a rectangle so as there is mentioned 2(l+b) the breadth will be the same i.e 96 km

So your answer is 96 km

Hope it helps you!!

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
