Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	The base of a triangle is 24 feet, and its area is 144 square feet. Calculate its height.
2	Formula	The area of a triangle is	Area = \$(1/2)\$ × base × height
3	Step	The base of a triangle is	24 feet
4	Step	The area of a triangle is	144 sq.feet
5	Step	To calculate the height of a triangle, we need to substitute the values in the formula	Area = \$(1/2)\$ × base × height 144 = \$(1/2)\$ x 24 x height
6	Step	Simplification	144 = 12 x height
7	Step	Divided 12 on both sides	\$(height \times 12)/12 = 144 / 12\$
8	Step	After performing division,the value we get	height = 12
9	Step	Then the height of a triangle is 12 feet.

Problem

The base of a triangle is 24 feet, and its area is 144 square feet. Calculate its height.

Formula

The area of a triangle is

Area = \$(1/2)\$ × base × height

Step

The base of a triangle is

24 feet

Step

The area of a triangle is

144 sq.feet

Step

To calculate the height of a triangle, we need to substitute the values in the formula

Area = \$(1/2)\$ × base × height

144 = \$(1/2)\$ x 24 x height

Step

Simplification

144 = 12 x height

Step

Divided 12 on both sides

\$(height \times 12)/12 = 144 / 12\$

Step

After performing division,the value we get

height = 12

Step

Then the height of a triangle is 12 feet.

SumUp
