Question

wirte the following information in mathematical form the length of a rectangle is twice its beradth and its perimeter is 52.

Answer 1

length =2breadth
perimeter of rectangle = 2(l+b)
52=2(l+b)
52=2(2b+b)
52=2(3b)
52/2=3b
26=3b
26/3=b
breadth of rectangle is 26/3
length of rectangle is 2(26/3) =52/3
