- [Fraction] Factor numerator:

- [Fraction] Factor denominator:

- [Fraction] Divide:

P = 2l + 2w
P = 2(8.4) + 2(4.8)
P = 16.8 + 9.6
P = 26.4cm
41 because if you separate the parts the square and the triangle then you would have a square that is 16 sq in diameter and a triangle that is 25sq in diameter
