Question

In rectangle ABCD, if lengths of AC and BD are (24y - 109) cm and (11y - 31) cm, find the length of BD.

Answer 1

Answer : BD= 35

Explanation : AD = BD (DIAGONAL OF SAME RECTANGLE)

AD = BD (DIAGONAL OF SAME RECTANGLE)24Y-109 = 11y -31

AD = BD (DIAGONAL OF SAME RECTANGLE)24Y-109 = 11y -3124y-11y = 109-31

AD = BD (DIAGONAL OF SAME RECTANGLE)24Y-109 = 11y -3124y-11y = 109-3113y = 78

Y= 78/13

Y = 6 answer

BD = 11y-31

BD = 11y-31BD = 11×6-31

BD =66-31

BD =66-31BD= 35
