The area of a desk top is 8 ¾ square feet. If the length is 3 ½ft., find the width.2 ft.24 ft.30 ft.

Answer 1

2:1’2

Explanation:

Answer 2

Formula for Area of a rectangle :


`\boxed {\boxed {\text {Area of a rectangle = Length x Width}}}`


`\text {Given that the area is }8 (3)/(4)\ \ ft^2 \text { and the length is } 3 (1)/(2) \ ft,`


`8 (3)/(4) = 3 (1)/(2) * \text{ width}`

Find width:

`\text{ width} = 8 (3)/(4) / 3 (1)/(2)`

Change to improper fraction:

`\text{ width} = (35)/(4) / (7)/(2)`

Change divide fraction to multiplication fraction:

`\text{ width} = (35)/(4) * (2)/(7)`

Multiply them:

`\text{ width} = (5)/(2)`

Simplify to mixed number:

`\text{ width} = 2(1)/(2) \text{ ft}`


`\boxed {\boxed {\text {Answer : Width = } 2(1)/(2) \text {ft. } }}`
