Step1 : draw a rough sketch and mark the measurements given.
Step 2 : draw △AMP using SAS construction rule with measures AM = 5cm, ∠M=90∘ and MP = 5 cm.
Step 3 : construct ∠P=60∘ and draw PY.
Step 4 : with center ‘P’ and radius 5cm (PL = 5 cm) draw an arc to intersect PY at L. Join L,P . LAMP is the required quadrilateral.
