El área de un cuadrado es de 625cm. Averigua cuánto mide el lado y cuánto mide el perímetro del cuadrado
Rzqust [24]

Respuesta:

Largo del lado = 25cm

Perímetro = 100 cm

Explicación paso a paso:

Área de un cuadrado = L²

L es la longitud del lado del cuadrado

Dado

Área del cuadrado = 625sq. cm

625 = L²

L = √625

L = 25

Por lo tanto, el lado mide 25 cm de largo.

Perímetro del cuadrado = 4L

Perímetro del cuadrado = 4 (25)

Perímetro del cuadrado = 100cm

Por lo tanto, el perímetro del cuadrado es de 100 cm.

Please help me out with this
olga_2 [115]

Answer:

10.4 cm

Step-by-step explanation:

The volume (V) of a pyramid is calculated using

V = \frac{1}{3} area of base × height (h)

area of square base = 6² = 36, thus

\frac{1}{3} × 36h = 120

12h = 120 ( divide both sides by 12 )

h = 10 cm

To find the slant height (s) consider the right triangle from the vertex to the midpoint of the base and from the midpoint of base to the side.

That is a right triangle with hypotenuse s and legs 10(h) and 3 (midpoint of the base )

Using Pythagoras' identity then

s² = 10² + 3² = 100 + 9 = 109

Take the square root of both sides

s = \sqrt{109} ≈ 10.4 cm
