Question

Solve question number 13
with full procedure

​

Answer 1

Area of equilateral∆= √3/4 side^2

$\implies\sf\ \dfrac{\cancel{\sqrt{3}}}{4}\times side^2=4\cancel{\sqrt{3}}\\ \\ \\ \implies\sf\ side^2= 4\times 4\\ \\ \\ \implies\sf\ side= \sqrt{4\times 4}\\ \\ \\ \implies\sf\ side=4cm$

Answer 2

Step-by-step explanation:

Here a is side of equilateral triangle

area of eq triangle = ✓3/4 a^2

4✓3 cm^2 = ✓3/4 a^2

4✓3 ÷ ✓3 * 4 = a^2

16 = a^2

✓16 = ✓a^2

4 cm = a

This is your answer
