An old sailing ship had a rectangular sail that was 7 meters high and had a perimeter of 56 meters. what was the area of the sail?

147 meter squared

Step-by-step explanation:

Assuming that by the definition of a rectangle, two sides share the same length, we can assume that two sides of the rectangle have sides of 7 meters. This means that the two remaining sides had a length of 42 meters combined. Divided between the two sides, this means that one pair of the sides is 42 meters, so 21 meters a side. Combing all of this information, we know the rectangle is 21 by 7 meters. To find the area, all you need to do is multiply the length times the width, so 7 times 21, which is 147 meters squared.

Hope this helps!

1.58 acres of land was planted on

Step-by-step explanation:

you will need to add up all the acres he used for each planting

find a common denominator to enable the addition for

1/3 + 3/4 + 1/2

the common denominator is 12

step 2 : divide the common denominator by each denominator then multiply the results by each numerator

1/3 + 3/4 + 1/2 =

for the tomatoes which is 1/3 it will be (12/3 * 1 ) ÷ 12 = 4/12

for corn which is 3/4 it will be ( 12/4 * 3 ) ÷ 12 = 9/12

for carrot which is 1/2 it will be ( 12/2 * 1 ) ÷ 12 = 6/12

step 3: since they all have a common denominator add up all the new numerators which will be

4/12 + 9/12 + 6/12 = 19/12 = 1.58 acres was used
