Answer 1

Hi friend,

x=23.43.... (1st term)

Multiply 100 on both sides

100x= 2343.4343... (2nd term)

Subtract first term from the second term

100x- x= 23.434343.....-2343.434343.....

99x=2302

x=2302/99

Hope it helps

2nd question -

Let the Length of side of equilateral triangle = a (cm)

Area of equilateral triangle = ✓3/4 × (a)²

4✓3 = ✓3/4 × a²

a² = 4✓3 × 4 / ✓3

a² = 4 × 4

a² = 16

a = ✓16 = 4 cm

Hence,

The Length of side of an equilateral triangle = a = 4 cm

HOPE IT WILL HELP YOU..... :-)

Answer 2

Step-by-step explanation:

let x = 23.434343 _(1eq.)

×ing both sides of (eq.1) by 100

100x = 23.434343/1000000×100

100x = 2343.4343

100x = 2320.0000+23.4343

100x = 2320+x

100x-x = 2320

99x = 2320

x = 2320/99

hope this helps u
