Question

In ΔNOP, p = 2.5 cm, n = 2.3 cm and ∠O=71°. Find the area of ΔNOP, to the nearest 10th of a square centimeter.

Answer 1

The area of the triangle is expressed as 2.718cm²

Area of a triangle

The formula for calculating the area of a triangle is expressed as:

A = 0.5absinФ

• a and b are the sides
• Ф is the angle

Given the following

• p = 2.5 cm
• n = 2.3 cm and;
• ∠O=71°

Substitute the given parameters to have:

Area = 0.5(2.5)(2.3)sin71

Area = 2.718cm²

Hence the area of the triangle is expressed as 2.718cm²
