<h2>Answer:</h2><h2>The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle = bh .. (2)
substitute (1)in (2), we get
Area = (2h-3) h
10 = (2h-3) h
20 =
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
