Question

The expression \[\dfrac{1}2bh\] gives the area of a triangle where \[b\] is the base of the triangle and \[h\] is the height of the triangle. what is the area of a triangle with a base of \[7 \text{ cm}\] and a height of \[4 \text{ cm}\]? \[\text{ cm}^2\]

Answer 1

The area of a triangle with a base of 7 cm and a height of 4 cm is calculated by substituting the values into the formula A = ½ × b × h, yielding an area of 14 cm².

Step-by-step explanation:

The area of a triangle can be calculated using the formula A = ½ × b × h, where A is the area, b is the base, and h is the height of the triangle. To find the area of a triangle with a base of 7 cm and a height of 4 cm, we can substitute these values into the formula:

A = ½ × 7 cm × 4 cm

Calculating the right side of the equation, we get:

A = 3.5 cm × 4 cm = 14 cm²

Therefore, the area of the triangle is 14 cm².
