The diagonal of a rectangle is 34 cm. If its breadth is 16 cm; find its : (i) length (ii) area
Answers
Answer:
length hoga
Step-by-step explanation:
thank please brainiest me
AC2 = AB2+BC2 (By Pythagoras theorem)
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2 1156 = l2 + 256
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2 1156 = l2 + 256l2 = 1156 – 256
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2 1156 = l2 + 256l2 = 1156 – 256l2 = 900
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2 1156 = l2 + 256l2 = 1156 – 256l2 = 900l = √900 = 30 cm
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2 1156 = l2 + 256l2 = 1156 – 256l2 = 900l = √900 = 30 cmarea = l x b = 30 x 16 = 480 cm2
AC2 = AB2+BC2 (By Pythagoras theorem)(34)2 = l2 + (16)2 1156 = l2 + 256l2 = 1156 – 256l2 = 900l = √900 = 30 cmarea = l x b = 30 x 16 = 480 cm2 (i) 30 cm (ii) 480 cm2
