Question

abcd is a parallelogram in which AB=9.5cm and its perimetre is 30cm. find the length of each side of the parallelogram

Answer 1

we know a parallelogram has equal opposite sides 

so let the longer side be l =9.5 cm

and the adjacent side be b

so we have perimeter = 2(l+b) = 30 ⇒ l+b = 15 ⇒ 9.5 + b = 15 ⇒ b = 5.5 cm

so the sides are 9.5 cm , 5.5 cm , 9.5 cm , 5.5 cm

Hope it helps..... Please mark it as brainliest.......

Answer 2

$wkt \\ perimeter = length \times breadth \\ = > 30 = 9.5 \times b \\ = > 30 \times 9.5 = b \\ = > b = 285cm \\ therefore \\ ab = cd = 9.5m \\ bc = da = 285cm$
