The length of the side of a square is represented by x+2. The length of the side of an equilateral triangle is 2x. If the square and the equilateral triangle have equal perimeter, then the value of x is _______
Read Solution (Total 3)
-
- perimeter of square=4(x+2) & Perimeter of triangle=3(2x)
According to condition both are equal -> 4x+8=6x gives x=4 - 12 years agoHelpfull: Yes(8) No(1)
- parameter of equilateral triangle = 3a = 3*2x=6x.
parameter of square = 4a = 4*(x+2) = 4x+8.
6x=4x+8 => 2x=8 => x=4. - 12 years agoHelpfull: Yes(3) No(0)
- Square =4a => 4(x+2) => 4x+8
Equilateral triangle = 3(2x) =>6x
4x+8 = 6x
x=4 - 11 years agoHelpfull: Yes(0) No(2)
