Given HA = 7 cm and AN = 4 cm
Steps :
(i) Drawn a line segment HA = 7 cm.
(ii) At H, constructed HX ⊥ HA.
(iii) With H as centre, drawn an arc of radius 4 cm and let it cut at HX at D.
(iv) With A and D as centres, drawn arcs of radii 4 cm and 7 cm respectively and let them cut at N.
(v) Joined AN and DN.
(vi) HAND is the required rectangle.
Calculation of Area :
Area of the rectangle HAND = l × b sq.units
= 7 × 4 cm2
= 28 cm2
