The dimensions of a rectangle are 51 m and 49 m respectively while side of a square is 50 m. Which of the following statements is correct ?
A. Diagonal of the square and the rectangle are equal.
B. Diagonal of both the geometrical figures intersect at right angles.
C. The perimeters of both the geometrical figure are equal.
D. Both the geometrical figures are of the same area.
Answer: Option C
Solution(By Examveda Team)
(A) Diagonal of the rectangle :$$\eqalign{ & = \sqrt {{{\left( {51} \right)}^2} + {{\left( {49} \right)}^2}} m \cr & = \sqrt {2601 + 2401} \,m \cr & = \sqrt {5002} \,m \cr} $$
Diagonal of the square :
$$\eqalign{ & = 50\sqrt 2 \,m \cr & = \sqrt {5000} \,m \cr} $$
(B) Diagonal of a square intersect at right angles but those of a rectangle do not.
(C) Perimeter of rectangle :
= 2(51 + 49) m
= 200 m
Perimeter of square :
= (4 × 50) m
= 200 m
(D) Area of rectangle :
= (50 × 50) m2
= 2500 m2
