Question

solve this problem
With explanation ​

Answer 1

area of equilateral triangle =

(root^3)/4×side^2

1.73/4×side= 43.25

side= 43.25 ×4/1.73

side= 173/1.73

side= 100cm

therefore,

side = 10m

hence,

option(c) is correct.

Answer 2

Answer:

10 cm

Step-by-step explanation:

Area of equilateral triangle = √3 / 4 × side²

                            43.25 cm²= √3 / 4 × side²

∴                    43.25 × 4 / √3= side²

∴                  43.25 × 4 / 1.73= side²  

∴                                   side²= 100

∴                                   side = √100 = 10 cm
