i) Base of the tile: 3.5 cm.

ii) Height of the tile: 8 cm.

1) Concept:

Use the given formula for area of a triangle.

2) Calculation:

The tile edging for a bathroom is in the shape of a triangle.

The area of a triangle with base b and height h is

A=12bh

But b=3.5 cm and h=8 cm.

Replace b and h by 3.5 and 8 respectively.
