A rectangular vegetable garden, for which 28 m and a width of 20 m, is sown with radishes, carrots and beets. Radish occupies 160 m, carrots – 2 times more than radish. How many square meters of garden are the beets occupied?
Let’s find the area of the vegetable garden. As you know, the area of a rectangle, which is a vegetable garden, can be found by multiplying its length by width, or:
S = a * b.
S = 28 * 20 = 560 m2 garden area.
Now let’s find how many m2 are sown with carrots. We know that there are 2 times more carrots than radishes, and there are 160 m2 of radishes. So, you need to multiply the area of the radish by 2:
160 * 2 = 320 m2 area occupied by carrots.
Now, to find the area occupied by beets, you need to add the areas of radish and carrots together, and subtract their total area from the total area. Let’s find the total area of radishes and carrots:
160 +320 = 480 m2 area occupied by radishes and carrots.
It remains to subtract the area occupied by radishes and carrots from the total area:
560 – 480 = 80 m2 beet area.
Answer: 80 m2 of the vegetable garden is occupied by beets.
