The width and length of a rectangular flower bed are in the ratio 5:7. The width is 40 feet. What is the length?
anzhelika [568]

Answer:

56 feet

Step-by-step explanation:

The width and length of a rectangular flower bed are in the ratio 5:7. The width is 40 feet. What is the length?

From the above question, our ratio is given as:

Width : Length

5 : 7

Width = 40 feet ,

To solve for the Length, let us represent the length as x

Width/Length

= 5/7 = 40/x

Cross Multiply

5 × x = 7 × 40

x = 7 × 40/5

x = 56 feet

Hence: The length of the rectangular flower bed = 56 feet
