Let's begin by listing out the information given to us:
This is a rectangle. A rectangle has its opposite sides congruent and adjacent sides form a right angle
Width (W) = 53 in,
Length (l) = 29 in
We will calculate the diagonal of the rectangle using the Pythagoras Theorem as shown below:
d² = 53² + 29²
d² = 2809 + 894 = 3650
d² = 3650
We take the square of both sides we have:
d = 60.415 ≈ 60.42
d = 60.42
