1. If JK= 3x and JM= 6x, find the value of x if the perimeter of the kite is 90cm.
2. If OJ= 3x+5 and OL= 2x+15, find the value of x
3. If KM = 18 cm, JL=12 cm, find the area of the kite JKLM.

Step-by-step explanation:
1.
JK = JM = 90
3x = 6x =90
= 6x-x3 =90
= 3x = 90
x = 30
2.
OJ = OL
3x+5 = 2x+15
3x-2x = 15-5
1x = 10
x = 10
3.
KM = JL
18 = 12
18 -12
JKLM = 6 erea
