1.The diagram shows a strip of wood ABCDE. AB = BC = CD = x cm.
DE is twice the length of CD.
Express the total length, AE, in terms of x. Give your answer in its simplest form

2. Tahir is h cm tall. Sienna is 4 cm shorter than Tahir.
Write an expression in terms of h for Sienna’s height in centimetres.

Answer 1

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

2.
T=h cm
S=h cm-4
