Question

What's the perimiter of a square when its sides are 3x+6 and 5x?

Answer 1

2(3x+6) + 2(5x)
= 16x +12

Answer 2

Perimeter = 2(L+B)
= 2( (3x+6) + (5x))
= 2( 8x+6)
= 16x+12

Answer 3

but since its a square, x = 3 so the perimeter is 60 :)

Answer 4

why is x=3?

bcuz its a square --> 3x +6 = 5x --> x=3

Answer 5

So x=3?

Answer 6

ya....and the perimeter is 60
