Answer:
ratio=9.899:7
Step-by-step explanation:
length of each side of a square=7 cm
by considering any 1 diagonal of the square,
1. the square is divided into 2 equal triangles whose area is equal which means 2 isosceles triangles are formed
we are considering triangle abc,
by pythagoras theorem,
(ac)^2=(ab)^2 + (bc)^2
=>(ac)^2 = (7)^2 + (7)^2
=>(ac)^2 = 98
=>ac =9.899
length of each diagonal of the square of side 7 cm is 9.899cm.
ratio of diagonal to side = 9.899 : 7
