Answer:
P=76 cm / A=310 cm²
Step-by-step explanation:
The perimeter is the sum of all sides in a polygon;
P=20+18+10+5+10+13= 76 cm
The area which i will divide into 2 parts and add them;
The rectangle of length 20 cm and width 13 cm;
A=lw=20×13=260 cm²
The rectangle of length 5 cm and width 10 cm;
A=lw=5×10=50 cm²
A(Total)=260+50= 310 cm²
