We know that the formula for the Area, A of a triangle is given as:
.....(Equation 1)
In our question we already know that and
Substituting these values in (Equation 1) we will get:
Multiplying both sides by 2 we will get:
In-order to find base we will isolate it by dividing both sides by 15. Thus, we get:
Thus, the answer is, base=27 mm.

The first formula most encounter to find the area of a triangle is A = 1⁄2bh. To use this formula, you need the measure of just one side of the triangle plus the altitude of the triangle (perpendicular to the base) drawn from that side. The triangle below has an area of A = 1⁄2(6)(4) = 12 square units.
Answer:
D
Step-by-step explanation:
As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.
Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)
The option A is incorrect due to the same problem for the point (8,7)
The correct option is D.
