Question

In figure one pair of adjacent sides of a parallelogram is in ratio3:4.If one of its angles,<A is a right angle and diagonal BD=10cm,find--

1. length of the sides of parallelogram...2.perimeter of the parallelogram..

Answer 1

in that figure
by Pythagoras theorem

AD^2 + AB^2 = DB^2
9X^2 + 16X^2 =100
25X^2 = 100
X^2 = 4
X = 2

SIDES are 3x = 6cm
4x = 8cm

perimeter = 6 + 8 + 6 + 8{as opp sides of parallelogram are equal}

peri. = 28cm
