A rectangle is 2.5 times as long as it is wide. Find the dimensions of the rectangle if it is perimeter is 56 cm.

I need a help with this question plz and what are the steps to find the right answer!!



Answer :

perimeter of a rectangle = 2 (length + breadth)
or, 56 = 2(2.5 breadth + breadth)
or, 56 = 7*breadth
breadth = 56*7 = 8 cm
length = 2.5*8 = 20 cm
