Question

5. Last year, Mr. Petersen's rectangular garden had a width of 5 meters and an area of 20 square meters.

Answer 1

Answer:

Last Year Length = 4 meters

This Year Length = 12 meters

This Year Width = 10 meters

Step-by-step explanation:

We know, area of the rectangle is given by the formula:

Area = Length * Width

Given width = 5

Area = 20

We solve for Length:

Area = Length * Width

20 = Length * 5

Length = 20/5 = 4

Last Year Length = 4 meters

Now, this year, the length would be 3 times as long, so new length would be:

This Year Length = 4 * 3 = 12 meters

This year, the width would be two times previous year, so width would be:

This Year Width = 5 * 2 = 10 meters
