Question

the distance round the rectangle is 20cm. if the length is 6cm, what is the width

Answer 1

perimeter of rectangle =l*b

20cm =2(6+x)

10-6=x
4cm=x

Answer 2

length = 6 cm

perimeter= 20 cm

breadth = perimeter-(2length)/2

= 20 - (2 x 6) /2

= (20 - 12) /2

= 8 /2

= 4

answer = breadth is 4 Cm
