Textbook Problem

△ A B C is an obtuse triangle with obtuse angle A. △ D E F is an acute triangle. How do the areas of △ A B C and △ D E F compare?Exercises 7, 8

To determine

To Compare:

The areas of ABC and DEF.

Explanation

Given,

The area of the first triangle (Î”ABC):

Here, b=8Â andÂ h=6

Area of the triangle

A=12bh

=12(8)(6)

=482

A=24Â unit2

The area of the second triangle (Î”DEF):

Here, b=8Â andÂ h=6

Area of the triangle

A=12bh

=1
