Question

The length of each of two equal sides of isosceles triangle is 4m less than twice the length of third side find the dimensions of triangle if it's perimeter is 57m

Answer 1

let the length of each uqual side be xm and length of unequal side be ym.
a/q
X=2y_4.....,..1
and perimeter =57m
57=2x+y ..........2
putting the value of X in 2equation
57=4y_8+y
65=5y
y=15m
then X=2×15_4=26........... I think your question is wrong ....
