Problema Solution
a triangle with equal sides and a square have the same perimeters. the length of a side of the triangle is 2x + 2. the length of a side of the square is x + 8. write and solve an equation to find the number.
Answer provided by our tutors
Let 't' and 's' stand for the length of one side of the triangle and the square, respectively. We can write:
3t=4s
t=2x+2
s=x+8
Combining these, we get:
3(2x+2)=4(x+8)
x=13
