Expert Answer:

begin mathsize 16px style Steps space of space construction colon
1 right parenthesis space Draw space BC space equals space 5 space cm
2 right parenthesis space At space straight B comma space construct space angle XBC equals 45 degree
3 right parenthesis space With space straight C space as space centre space and space radius space 4 space cm comma space draw space an space arc space cutting space BX space at space straight P.
Thus comma space BCP space is space the space required space triangle.
4 right parenthesis space SInce space straight P space is space equidistant space from space AB thin space and space BC comma space straight P space lies space on space bisector space of space angle ABC.
rightwards double arrow angle ABC equals 90 degree
rightwards double arrow straight A space lies space on space the space perpendicular space to space BC space at space straight B.
5 right parenthesis space Construct space QB perpendicular BC.
6 right parenthesis space Construct space RC perpendicular CB.
7 right parenthesis space Since space straight P space is space equidistant space from space straight C space and space straight D comma space PC equals PD
8 right parenthesis space With space straight P space as space centre space and space radius equals PC comma space draw space an space arc space to space meet space CR space at space straight D.
9 right parenthesis space With space straight B space as space centre space and space radius equals CD comma space draw space an space arc space to space meet space BQ space at space straight A.
Join space AD.
Length space AB space equals space 5.5 space cm space approximately. end style
