18. The area of a right triangle is 30 cm². The length
1 answer:
Answer:
12
Step-by-step explanation:
The area of a triangle is calculated with the following formula:
(b: base, h: height (or legs))
We can use this formula to find the length of the other leg:
30 = multiply both sides with 2 to get rid of fraction
60 = b*h one of the leg's length is given as 5 so
60 = 5*h divide both sides by 5
12 = h is the length of the missing leg.
