Question
mohammed grew a garden last year. his plot of land was 6\frac{3}{4} feet by 10 feet. he wants to have twice as much area in his garden this year. how much area will the new garden take up? a 52\frac{1}{2} ft.^{2} b 67\frac{1}{2} ft.^{2} c 127 ft.^{2} d 135 ft.^{2}
Step1: Calcular el área del jardín del año pasado
Convertir \(6\frac{3}{4}\) a fracción impropia: \(6\frac{3}{4}=\frac{6\times4 + 3}{4}=\frac{27}{4}\)
El área del jardín del año pasado es \(A_1=\frac{27}{4}\times10=\frac{27\times10}{4}=\frac{270}{4}=\frac{135}{2}=67.5\) pies cuadrados
Step2: Calcular el área del nuevo jardín
El nuevo jardín debe tener el doble de área que el del año pasado. Entonces \(A_2 = 2\times A_1\)
\(A_2=2\times67.5 = 135\) pies cuadrados
