Question

Which of the following statement is not true

Perimeter of an equilateral triangle is 3xside
To find cost of painting a wall one must know the area of the wall
width of a rectangle is Area/length
Side of a square is area/4

Answer 1

Answer:

Statement 'Side of a square is area/4' is not true

Hope it helps

Answer 2

The statement which is not true is: "Side of a square is area/4". (option fourth)

• The perimeter is defined as the measure of distance or length around a 2-dimensional shape or figure. Thus, as an equilateral triangle has all sides equal, its perimeter will be = (side + side + side) that is, (3×side). So, option 1 is true.
• The rate of painting a wall will usually be given in price per (meter)². So if we know the area of the wall, we can find the cost of painting a wall. Thus, option 2 is true.
• Since for a rectangle, we know that area = length×width. On rearranging we get, $width=\frac{area}{length}$. So, option 3 is true.
• The area (A) of a square is given by (side)². That is, $A = (side)^{2}$, so, the side can be determined as $side = \sqrt{A}$, and not A/4. Hence, the statement in option 4 is not true.
