Actually, the area of a triangle is a = bh/2. If a = 30 and b = 12:
So he height is 5 units
Answer:
2x= 38.5
Step-by-step explanation:
I'm not sure where u got 12x but 2 x = 38.5:
2x + 5 =82
subtract 5 for 82
2x = 77
77 divided by 2 is 38.5
x = 38.5
hope this helps :)

Answer:
LA = 624 cm²
Step-by-step explanation:
h² = 5² + 12²
h = 13
LA = 4 × bh/2
LA = 4 × (24 cm)(13 cm)/2
LA = (48 cm)(13 cm)
LA = 624 cm²
