Question

What is the area of the obtuse triangle given below? 13. 15

O A. 154 sq. units
B. 48.75 sq. units
C. 97.5 sq. units
D. 195 sq. units

Answer 1

C. 97.5 sq.units

Here, formula to calculate area of obtuse triangle is,

A=1/2 x (base x height)

In the given question let,

base(b)=13

height(h)=15

Then,

A=1/2x(bxh)

A=1/2x(13x15)

A=97.5 sq.units
