attashe74 [19]

Respuesta:

25 cm²

Explicación paso a paso:

El área A de un rombo tiene:

A = pq / 2

Donde pyq son las diagonales

Tomando p como la diagonal más grande = 10 cm

Diagonal más pequeña, q = 1/2 * 10 = 5cm

Por lo tanto, el área del rombo es:

A = (10 * 5) / 2

A = 50/2

A = 25 cm²

Answer:

A.102%

Step-by-step explanation:

Let cost price of painting=$100

In first year price increased 20%

Then , the price=100+100(0.20)=$120

In second year

Price decreased 15%

Then , the price of painting=120-120(0.15)

The price of painting=$102

Percent =\frac{final\;price}{Initial\;price}\times 100

By using this formula

Then, we get

Percent of the original price=\frac{102}{100}\times 100

Percent of the original price=102%

Option A is true.
