Answer 2

Intro.

Before we solve the areas of the triangles, let's review the key points.

Key points:

• Area of triangle: 1/2 x Base x Altitude

Solution (4):

• 1/2 x 13.5 x 10.6
• => 1 x 13.5 x 5.3
• => 71.55 cm²

Solution (5):

• 1/2 x 7.2 x 4
• => 1 x 7.2 x 2
• => 14.4 yd²

Solution (6):

• 1/2 x 6 x 5.2
• => 1 x 3 x 5.2
• => 15.6 ft²

Hoped this helped!
