Problem

Find the height of a triangle whose area of 420 cm² and a base of 60 cm.

Step

Given base (b)
Area of triangle(A)

60 cm
420 cm²

Formula:

Area of Triangle

\$(1/2) \times (b) \times (h)\$

Step

We are currently determining the height value (h).

\$(2 * A)/b\$

Step

Substitute the values

\$(2 * 420(cm)^2)/60 cm\$
\$840(cm)^2/60cm\$ = \$8 cm\$

Step

Therefore, the height(h) of the triangle is

\$8 cm\$
