8. The area isosceles triangle

The isosceles triangle's area is easier to work out because it has a consistent growth in height which happens at the same rate and time that the growth of all its sides seeing as they're all equal. It's because of this that the triangle's height always exists at a ratio that is 88/100 to its base. This then makes it easier to measure the isosceles triangle's area using the length of one of its sides. The formula for measuring the area of the isosceles triangle can then get noted down as its base squared multiplied by 0,88 divided by 2.

Measurement Formula: base² × 0,88 × ½ or base² × 0,44.
