Question

Mark 1

Maria bought a rectangular tablecloth. If the length of the tablecloth is three times its breadth and the perimeter is 720 cm, find the length of the tablecloth.

Answer 1

x= width

3x = the length

perimeter = 720cm

P =2(length+width)

720 = 2(x+3x)

720 = 8x

x= 720/8=90

width = 90cm

length = 270cm
