Answer:

area ≈ 59.6 units²

Step-by-step explanation:

Calculate the area (A) of the triangle using

A = [tex]\frac{1}{2}[/tex] ac sinB

That is one half the product of the 2 sides and the sine of the included angle, thus

A = [tex]\frac{1}{2}[/tex] × 11 × 11 × sin100° ≈ 59.6 units² ( to the nearest tenth )
