Answer: Approximately 12.3 units^2
Step-by-step explanation:
I used an online graphing calculator called 'Desmos'. It's really convenient if you are too lazy to manually draw graphs or are in a hurry.
Area = 0.5 x Base (b) x Height (h)
= 0.5 x 7 x 3.5
= 49/4
= 12.25
Approximately 12.3 units^2.
The formula used for calculating the area of the triangle is only applicable if there is a right angle in a triangle. Basically, this formula is only used for right-angled triangles.
