A square sheet of paper measures 25 centimeters on each side. What is the length of the diagonal of this paper?
Varvara68 [4.7K]

Answer:

35.36 cm

Step-by-step explanation:

The diagonal of a square will be given by

D=\sqrt {a^{2}+b^{2}}

Where a is the length of one side and b is the length of another side. For a square, botj sides are equal hence the diagonal calculations will be as follows

Given that a is 25 then

D=\sqrt {25^{2}+25^{2}}

D=35.3553390593274

Rounding off the nearest two decimal place

D=35.36 cm

Which of the following represents the area of a rectangle whose length is 3x + 5 and whose width is x − 2? 3x2 − x − 10 3x2 − 10
never [62]
A = L * W
L = 3x + 5
W = x - 2

A = (3x + 5)(x - 2)
A = 3x(x - 2) + 5(x - 2)
A = 3x^2 - 6x + 5x - 10
A = 3x^2 - x - 10 <====
