Chapter 11: Q5. (page 431)

Find the area of each figure:
An equilateral triangle with sides $8 f t$

Short Answer

Expert verified

The area of given figure is $16 \sqrt{3}$ square units.

Step by step solution

Step 1. Given information.

The side of an equilateral triangle $a = 8$ .

Step 2. Concept used.

Area of equilateral triangle can be found using the formula

$A = \frac{\sqrt{3}}{4} a^{2}$

Where,

$a =$ Side of an equilateral triangle.

Step 3. Find the area of given figure.

$A = \frac{\sqrt{3}}{4} a^{2}$

$= \frac{\sqrt{3}}{4} {(8)}^{2}$

$A = \sqrt{3} \times 8 \times 2$

$= 16 \sqrt{3}$ Square units.

Therefore, the area of given figure is $16 \sqrt{3}$ square units.
