Question

The perimeter of a rectangle is 18 3/4m. If the length of the rectangle is twice the breadth, find the area of the rectangle.​

Answer 1

Answer:

area of rectangle is 625/32 square meter

Answer 2

Answer:

19.22m²

Step-by-step explanation:

We know the perimeter is 18 3/4m, which can be turned into 18.75m instead.

We can label the breadth as x, because we do not know its actual length.

Since the length is twice the breadth, we can call it, 2x.

In a rectangle there are 4 sides, 2 lengths, and 2 breadths (widths).

Therefore, to make a rectangle using our labels, we would get

x+2x+x+2x= perimeter, which is 18.75

3x+3x= 18.75

6x=18.75

x= 18.75/6

x= 3.1 to 1 decimal place.

We can substitue this answer into our breadth and lengths, so

breadth= 3.1m

length= 6.2m

Now, we can find the area, which is length×breadth, so, 3.1×6.2 which is 19.22m²

Hope this helps :)
