Question

67.) triangle with base - related side 3 m and height 1.9 m 68.) triangle with base 6 ft and height 4 ft

Explanation:

Assuming the problem is to find the area of the triangles:

For Problem 67 (Triangle with base 3 m and height 1.9 m)

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times \text{base} \times \text{height}$.

Step2: Identify the base and height

Here, the base is $3$ m and the height is $1.9$ m.

Step3: Substitute the values into the formula

$A = \frac{1}{2} \times 3 \times 1.9$

Step4: Calculate the result

First, calculate $3 \times 1.9 = 5.7$. Then, $\frac{1}{2} \times 5.7 = 2.85$.

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times \text{base} \times \text{height}$.

Step2: Identify the base and height

Here, the base is $6$ ft and the height is $4$ ft.

Step3: Substitute the values into the formula

$A = \frac{1}{2} \times 6 \times 4$

Step4: Calculate the result

First, calculate $6 \times 4 = 24$. Then, $\frac{1}{2} \times 24 = 12$.

Answer:

The area of the triangle in problem 67 is $2.85$ square meters.

For Problem 68 (Triangle with base 6 ft and height 4 ft)
