Question

that has an area of 30 square units and a base measuring 12 units. 3 units 5 units 8 units 9 unitsThe formula for the area of a triangle is , 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 12 units. 3 units 5 units 8 units 9 units

Answer 1

Answer:

base could either be 12 or 5 and the height could be the other

Step-by-step explanation:

Area of triangle = bh/2

30 = bh/2

60/bh

base could either be 12 or 5 and the height could be the other

(12)(5)/2 = 30

Answer 2

Answer: 5 units

Step-by-step explanation:

The formula to find the area of a triangle is given by :-

$\text{Area}=\dfrac{1}{2}\text{ base * height}$

Given : The area of a triangle = 30 square units

The length of the base of the triangle = 12 units

Let h be the height of the triangle .

Then , we have

$30=\dfrac{1}{2}12\times h\\\\\Rightarrow\ h=\dfrac{30}{6}\\\\\Rightarrow\ h=5\text{ units}$

Hence, the height of a triangle = 5 units
