These two figures are similar. What is the value of x? Enter your answer, as a decimal rounded to the nearest tenth, in the box.

x = Two quadrilaterals. First quadrilateral has one angle which has 1 arc, two opposite angles which have two arcs each, and the fourth angle, which is opposite the angle with 1 arc, has 3 arcs. The two sides that are each between the angle with 1 arc and an angle with 2 arcs are each labeled 18 centimeters. The two sides that are each between the angle with 3 arcs and an angle with 2 arcs are each labeled 22 centimeters. The second quadrilateral also has one angle which has 1 arc, two opposite angles which have two arcs each, and the fourth angle, which is opposite the angle with 1 arc, has 3 arcs. A side between the angle with 1 arc and an angle with 2 arcs is labeled 15 centimeters. A side between the angle with 3 arcs and an angle with 2 arcs is labeled x centimeters.

calcular lo que costará sembrar césped en un jardín de forma triangular de base 25 m y de altura 15m si cada metro cuadrado de c
olasank [31]

Answer:

$3,750

Step-by-step explanation:

In english:

First we need to calculate the area of the garden. As it is a triangle we calculate the area as:

area = (base*height)/2

The base is 25m and the height 15m, so the area is:

area = 25*15/2 = 187.5 m2

As each m2 costs $20, for the whole cost we need to calculate the product between 187.5 m2 and $20:

cost = 187.5 * $20 = $3,750

Total cost: $3,750

In spanish (en espanol):

Primero necesitamos calcular el área del jardín. Como es un triángulo calculamos el área como:

área = (base * altura) / 2

La base mide 25 my la altura 15 m, por lo que el área es:

área = 25 * 15/2 = 187.5 m2

Como cada m2 cuesta $ 20, para el costo total necesitamos calcular el producto entre 187.5 m2 y $ 20:

costo = 187.5 * $ 20 = $ 3,750

Costo total: $3,750
