Question

Directions: Find the area of each figure.(Hint: Round to the nearest tenth)26 ftBlank 1:

Answer 1

EXPLANATION

This is an equilateral triangle, so the area is given by the following relationship:

`\text{Area}_{\text{equilateral}-\text{triangle}}=\frac{\sqrt[]{3}}{4}a^2`

Where a is the side length:

`\text{Area}_{\text{equilateral}-\text{triangle}}=\frac{\sqrt[]{3}}{4}(26)^2`

Computing the power:

`\text{Area}_{\text{equilateral}-\text{triangle}}=\frac{\sqrt[]{3}}{4}676`

Simplifying numbers:

`\text{Area}_{\text{equilateral}-\text{triangle}}=\sqrt[]{3}(676)/(4)=169\sqrt[]{3}=292.7ft^2`

The answer is 292.7 ft^2
