Answer 2

Answer:

The base of a triangle(b) = 12 cm or 1.2 dm

Step-by-step explanation:

Given,

The altitude of a triangle(h) = 8 cm = 0.1 × 8 dm

= 0.8 dm and

The area of a triangle = 0.48 dm²

To find, the base of the triangle(b) = ?

We know that,

Area of a triangle = 1/2 × b × h

⇒1/2 × b × 0.8 = 0.48

⇒b × 0.4 = 0.48

⇒b = 0.48/0.4

⇒b = 1.2 dm or 12 cm

Hence, the base of the triangle (b) = 12cm or 1.2 dm
