Question

the area of a square

Answer 1

Area of square= area of rectangle
(Side)*2=l×b
Side*2=16×9
Side=√144
Side of square =12
Perimeter of square 4×side
Perimeter of square=4×12
Perimeter of square=48

Diagonal of square =√2 ×side
=√2×12
=12√2
Now diagonal of rectangle =√l*2+b*2
=√(16)*2+(9)*2
=√256+81
=√337
