Question

find the area of a rhombus each
side of which measure 20 centimetre and one of whose diagonal is 24 cm

Answer 1

Given:Side of the rhombus=20 cm Length of a diagonal=24 cmWe know: If d1 and d2 are the lengths of the diagonals of the rhombus, thenside of the rhombus=12d12+d22So, using the given data to find the length of the other diagonal of the rhombus:20=12242+d2240=242+d22Squaring both sides to get rid of the square root sign:402=242+d22d22=1600-576=1024d2=1024=32 cm∴ Area of the rhombus=12(24×32)=384 cm2
