Explanation:
#"the area (A) of a kite is equal to half the product of"#
#"the diagonals"#
#•color(white)(x)A=1/2xxd_1xxd_2#
#"where "d_1" and "d_2" are the 2 diagonals"#
#"let "d_1=17" we have to find "d_2#
#"substitute known values into the formula"#
#34=1/2xx17xxd_2#
#"multiply through by 2"#
#68=17d_2#
#"divide both sides by 17"#
#68/17=d_2rArrd_2=4#
#"the length of the other diagonal "=4" cm"#
