Answer:
The height of a triangle that has an area of 30 square units and a base measuring 12 units is 5 units.
Explanation:
The formula for the area of a triangle is A=1/2bh, where b is the length of the base and h is the height.
Find the height of a triangle that has an area of 30 square units and a base measuring 12units.
A = 1/2bh
h = 2A : b
h = 30 x 2 : 12
h = 60 : 12
h = 5
---------------------
A = 1/2 bh
A = 1/2 x 12 x 5
A = 6 x 5
a = 30 units²
