Question 992784: Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If the perimeter is 49 ft, how long is each side?
Which equation represents this?
You can put this solution on YOUR website! Hi there,
Dwayne's garden is an isosceles triangle.
Two equal sides (and two equal angles)
Length of an equal side = 'x'
Length of other side(s) = x + 4
Perimeter = the 3 sides added together.
49 = x + x + (x + 4)
49 = x + x + x + 4
Collect like terms
3x = 49 - 4
3x = 45
x = 15.
Two equal sides = 15 ft
Third side = 19 ft
Hope this helps :-)

----
Sketch a picture of this isosceles triangle: equal sides are "x"; base = (x+4).
Equation:
x + x + x+4 = 49
3x = 45
x = 15 (length of each of the equal sides)
x+4 = 19 (length of the base)
