Question

Peter is making an "X marks the spot" flag for a treasure hunt. The flag is made of a square white flag with sides

Answer 1

Answer:

34 centimetres

Step-by-step explanation:

Since the flag is made of a square white flags, then all its sides are equal in length. a diagonal of a square would divide it into two equal triangle.

Let the length of the diagonal be represented by t, such that;

$/hyp/^{2}$ = $/adj 1/^{2}$ + $/adj 2/^{2}$

$t^{2}$  = $(12)^{2}$ + $(12)^{2}$

           = 144 + 144

$t^{2}$  = 288

t = $\sqrt{288}$

t = 16.9706

t = 17 centimetres

The length of a diagonal of the flag is 17 centimetres.

So that,

The centimetres of ribbon required to make the "X" = 2 x diagonal

                                                            = 2 x 17

                                                            = 34

The centimetres of ribbon required to make the "X" is 34 centimetres.
