The dimensions of all parts of Triangle B is 4 times that of A
A = 1/2 b * h for the given triangle
A = 1/2 * 4b * 4h
A = 1/2 * 16 * b * h
A = 16 * (1/2 * b * h)
The area of the new triangle is 16 times the old.
16 * 15 = 240 cm^2
240 cm^2 <<<<< answer
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
