It is given that
A rectangle is divided into exactly 20 congruent squares
If they are lined up the Length is 36 inches
Therefore the length of each square or the side of the square = 36/20
= 1.8 inch
The area of the rectangle will be
20* Side of square * Side of square
=20*1.8*1.8
= 64.8 square inch

Answer:
Height is 40√2 m or 56.57 m
Explanation:
Use Pythagoras theorem: a² + b² = c²
where 'a' and 'b' are the legs and 'c' is the hypotenuse
Here given:
Substitute values:
(20)² + (h)² = 60²
400 + h² = 3600
h² = 3600 - 400
h² = 3200
h = √3200
h = 40√2
h = 56.6 meter
