Question
the area of a square frame is 55 square inches. find the length of one side of the frame. explain a. to the nearest whole inch b. to the nearest tenth of an inch a. the length of one side of the frame to the nearest whole inch is 7 in. explain. <55<, so <√55<. since 55 is closer to than to, √55 is closer to. (type integers or decimals.)
Step1: Encontrar cuadrados perfectos cercanos
$49 < 55 < 64$, entonces $\sqrt{49}<\sqrt{55}<\sqrt{64}$. Esto es, $7 < \sqrt{55}<8$.
Step2: Determinar la proximidad
55 está más cerca de 49 que de 64. Entonces $\sqrt{55}$ está más cerca de 7 que de 8.
Step3: Redondear a la décima más cercana
Calculamos $\sqrt{55}\approx 7.416$. Redondeando a la décima más cercana, obtenemos 7.4.
