Question

each side of a square checkerboardmeasurees 40 cm. what is is the length of the diagonal of the board

Answer 1

We can use Pythagoras Theorum. PythagorasTheorum is basically this: C squared = A squared + B squared. A is the length
of the chekerboard, B is the width of the checkerboard and C is the length of
the diagonal. So the checkerboard is square then both A and B are 40cm, we
would need to square each of them (so A^2 and B^2 instead of being 40cm becomes
1600cm^2 ) then we add them together (1600 plus 1600 = 3200) and after that we
find the square root of the answer ( the square root of 3200 = 56.569... so C is
equal to 56.569...( in other words the diagonal of the chekerboard is 56.6cm [
rounded of to the nearest tenth cm]
