The base of a triangle is 3.4cm. the area is 20.74cm. find the height to 1 dp

12.2 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the height )

Here A = 20.74 and b = 3.4 , thus

× 3.4 × h = 20.74 ( multiply both sides by 2 to clear the fraction )

3.4h = 41.48 ( divide both sides by 3.4 )

h = 12.2 cm

43

step-by-step explanation:

your answer would be 12
