What is the value of x? And what is the perimeter? NO LINK OR TROLL ANSWERS THEY WILL BE REPORTED! ANSWER ASAP!! WILL AWARD BRAINLIEST IF CORRECT!

Perimeter (P) = 70 cm

Perimeter is the distance around a two dimensional shape, or the measurement of the distance around something; the length of the boundary.

In simple words, perimeter is sum of all sides of a two dimensional shape.

So let us add length of all the sides of above polygon.

P = 12 + Y + 5 + 9 + 7 + X

[ But Perimeter, P = 70]

So,

70 = 12 + Y + 5 + 9 + 7 + X

70 = 33 + X + Y

Taking 33 on left hand side of above equation.

37 = X + Y

OR

X + Y = 37 (Equation 1)

From the above figure,

X + 9 =Y

Which implies,

X - Y = -9 (Equation 2)

Adding equation 1 and equation 2, we get

X + Y = 37

+ X - Y = -9

2 X = 28

X = 28 / 2

=> X = 14 (Equation 3)

So we have X = 14.

Again, X - Y = -9 [ from equation 2]

14 - y = -9

14 + 9 = Y

Which implies,

Y = 23

So X = 14 cm & Y = 23 cm.
