Answer:
The width of the rectangle is 2.3 m
Step-by-step explanation:
Now, when we are asked to find the area of the rectangle, we will use the formula: . We should be given with at least two values, and then we can use the above formula and can find the third variable.
Now, we are given that the area of a rectangle is 12.65 and the length measures 5.5 m
So the width is given as:
So this is the required with of the rectangle.
If any side is greter or equal to the sum of the other 2 sides then it is not a triangle.
So A is not a triangle because 24 > 11 + 11
For C 19 = 10 + 9 - not a triangle
D:- 23 > 4 + 7 Not a triangle.
Only B is a triangle
