c 10
d diagonals of rectangle do not bisect each other
Answer:
As given below
step by step explanation:
Given data
the length of the broom sticks set 1 = 6m
set 2 = 8 cm
Given questions
(a) Which of the following quadrilateral can be made with the given broom sticks (without breaking)?
(i) Rectangle (ii) Square (iii) Rhombus (iv) None
ans:- (i) Rectangle
∵ The lengths of sticks are different and 2 sticks are with same length
b) If Vishnu forms a quadrilateral with these brooms, what is the perimeter of the quadrilateral so formed?
(i) 20 cm (ii) 24 cm (iii) 28 cm (iv) 30 cm
ans:- (iii) 28 cm
if Vishnu formed a quadrilateral it will be a rectangle
then dimension of quadrilateral = 8 cm × 6 cm
perimeter of quadrilateral = 2(8+6) = 2(14) = 28 cm
(c) If Vishnu forms a Rectangle with these brooms, find the length of a diagonal.
(i) 10 cm (ii) 12 cm (iii) 16 cm (iv) 18 cm
ans:- (i) 10 cm
the diagonal of the rectangle d =
[ where a and b are sides of rectangle ]
⇒ d = √(6² + 8²)
d = √100 = 10 cm
(d) Which of the following properties of Rectangle is true?
i) Diagonals of rectangle are perpendicular.
ii) Diagonals of rectangle are equal.
iii) All sides of Rectangle all equal.
iv) Diagonals of Rectangle do not bisect each other
ans:- ii) Diagonals of rectangle are equal.
[ ∵ Diagonals of a rectangles are equal ]
(e) If Vishnu forms a square by breaking only two broom sticks, what is the length of the diagonal of the square formed?
i) 6 cm (ii) 2√6 cm (iii) 12 cm (iv) 3√6 cm
if Vishnu formed a square by breaking only two sticks then broken sticks will largest sticks which are 8 cm length
and the length of the side of the square will be 6 cm
here diagonal of the square d = √2 (6)
= 6 √2 cm
