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.

Do the side lengths 9,12,15 classify as a right,acute,obtuse triangle, or “no possible triangle”
HACTEHA [7]
Refer to c^2=a^2+b^2 (^2 means squared)
C is the hypotenuse and will be the longest measure
So 15^2= 9^2+12^2
225=225
If both sides are equal then the triangle is a right triangle, if the hypotenuse (or c) is lower or higher than you can determine whether it’s obtuse or acute
It would be a right triangle
