Given = 7.2 cm and BN = 9.7 cm
Steps :
(i) Drawn a line segment BA = 7.2 cm.
(ii) At A, constructed NA ⊥ AB.
(iii) With B as centre, drawn an arc of radius 9.7 cm and let it cut at AX at N.
(iv) With B as centre and AN as radius drawn an arc. Also with N as centre and BA as radius drawn another arc. Let then cut at D.
(v) Joined ND and BD.
(vi) BAND is the required rectangle.
Calculation of Area :
Area of the rectangle BAND = l × b sq.units
= 7.2 × 6.7 cm2
= 48.24 cm2
