b. 98 sq. units
c. 28 sq. units
d. 21 sq. units

question 6
what is the area of the obtuse triangle given below?
a. 209 sq. units
b. 104.5 sq. units
c. 52.25 sq. units
d. 154 sq. units

Explanation:

Question 4

Step1: Recall right triangle area formula

Area = $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

$\text{Area} = \frac{1}{2} \times 17 \times 8$

Step3: Calculate the result

$\text{Area} = \frac{136}{2} = 68$

Question 5

Step1: Recall triangle area formula

Area = $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

$\text{Area} = \frac{1}{2} \times 14 \times 7$

Step3: Calculate the result

$\text{Area} = \frac{98}{2} = 49$

Question 6

Step1: Recall triangle area formula

Area = $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

$\text{Area} = \frac{1}{2} \times 19 \times 11$

Step3: Calculate the result

$\text{Area} = \frac{209}{2} = 104.5$

Answer:

Question 4: C. 68 sq. units
Question 5: A. 49 sq. units
Question 6: B. 104.5 sq. units
