✔ 最佳答案
let the side of smaller square be x. the peimeter of the smaller square will be 4x.As the ratioa of perimeter of larger square is 1:4 to smaller square,
this means the perimeter of larger square is 4 times of the smaller square, therefore, the perimeter of larger square is 16x.
4x + 16x = 80
20x = 80
x = 4
Therefore the length of side of smaller square is 4(4) = 16cm
Therefore the length of side of larger square is 16(4)= 64 cm
