Problem-solving The length of square A is the same as the perimeter of square B. The area of square A is 75 cm2
Estimate... the length of square B

The first option would be correct if it were one half and not one

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Just tell koda to adjust the number of shapes himself.
