Set the length of the base as x, the two equal sides are then 4x each, so the perimeter is x+4x+4x=9x
The length of the shorter piece is 30
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions that are made up of constants, terms, factors and variables.
They also contain mathematical operations such as division, addition, multiplication, subtraction, etc
From the information given, we have;
Let the length of one piece be x
Let of the other piece is 5x
5x + x = 180
collect like terms
6x = 180
Make 'x' the subject
x = 180/ 6
x = 30
Thus, the length of the shorter piece is 30
