Question

Fred is fencing his yard, which is shaped as a rhombus. He used 4x meters of fencing material for one side and (x + 9) meters for the adjacent side.

What is the perimeter of the yard?
Answer







12 meters








36 meters








48 meters








96 meters

Answer 1

Perimeter = 2l + 2w
2(4x) + 2(x + 9)

Answer 2

10x + 18
??

Answer 3

Yes now find x

Answer 4

ok umm what do i do to find it

Answer 5

You want to find the value of x. So you have to put it alone on one side of the equation:
10x + 18 = 0
-18
10x = -18
/10
x = -1.8

Now put in x into the original equation to find the perimeter;)
2(4x) + 2(x + 9)
2(4(-1.8)) + 2((-1.8) + 9

Answer 6

Hold on a sec

Answer 7

i got -93.6 that cant be it
