Question

Constru construct a right construct a rectangle where one side is 3 cm and the diagonal is 5 cm

Answer 1

one side of rectangle = 3cm
and diagonal = 5 cm
as we know that all angles in a rectangle are 90 degree
so by pythagoras theorem
square of diagonal = sum of squares of two sides
5*5=3*3+ square of other side
25=9+sq of other side
25-9=sq of other side
16=sq of other side
length of that side = 4cm
