Question

The sides of two squares are 2.4 and 1.8 long respectively find the side of new square equal to the sum of the two squares in area

Answer 1

Area of 1st square = side^2

=2.4^2

=2.4*2.4

=5.76

Area of 2nd square = side^2

=1.8^2

=3.24

Sum of the areas=5.76+3.24

s^2=9

s=√9

s=3

Hope this helps
