apologiabiology · Answer

there are five points so the figure is a pentagon 
 AB=BC=CD=x cm 2x cm =DE so assume so AB+BC+CD+DE=x+x+x+2x or 5x=AE 
 
 T=h cm S=h cm-4

apologiabiology · Answer

The total length AE of the wood strip is expressed as 5x cm. Sienna's height, being 4 cm shorter than Tahir's height of h cm, is expressed as h - 4 cm.
