1.	1.I is an isosceles triangle. base is 3 times more than double the same sides. perimeter is 35 cm, so how long is leg?
Answer» Answer: 2L + B = 30 CM L = 2B 2(2B) + B = 30 cm 4B + B = 30 cm 5B =30 cm B = 30/5 cm = 6 cm L = 2B = 26 cm = 12 cm Each equal side is 12 cm. The base is 6 cm

Answer»

Answer:

2*L + B = 30 CM

L = 2*B

2*(2*B) + B = 30 cm

4*B + B = 30 cm

5*B =30 cm

B = 30/5 cm = 6 cm

L = 2*B = 2*6 cm = 12 cm

Each equal side is 12 cm. The base is 6 cm
