Mark as brainliest mate !
Step-by-step explanation:
Given side of square = 16cm
perimeter of square= the length of wire
= 4x16= 64cm
perimeter of square = perimeter of rectangle
64= 2(l+ b)
32=l+ 10
l= 22cm
ar of square = side²
= 16²= 256cm²
ar of rectangle= lxb
= 10x22= 220cm²
Therefore square has more area.....
