Question

A rectangle of perimeter 42cm is p cm long and q cm broad. If the difference between the length and breadth is 9 cm. What is p and q

Answer 1

hiI mate ur solution here.......

perimeter of rectangle= 2(l+w)

=> 42 = 2(P+q)

=> 21= p+q

& Diff of l&W = 9cm.

Then, P+q=21

P-q=9

=> 2P = 30

» P= 15cm

&

=> q = 6cm

.......I hope it's help...
