A Rectangular park dimensions are (3 + √2) and (2 + √2) units, then the area of that park in square unit.
A) 8 + 5√2
B) 5 + 2√2
C) 13√2
D) 5 + √2
Correct option is (A) 8 + 5√2 Area of park \(=(3+\sqrt{2})(2+\sqrt{2})\) \(=6+3\sqrt{2}+2\sqrt{2}+2\) = \(8+5\sqrt{2}\)
Correct option is (C) 3 Area of rectangular sheet \(=(\sqrt{5}+\sqrt{2})(\sqrt{5}-\sqrt{2})\) \(=(\sqrt{5})^2-(\sqrt{2})^2\) = 5 - 2 = 3 square units
Correct option is A) 8 + 5√2
Correct option is (A) bh Area of a parallelogram = Base \(\times\) Height = bh square units
Correct option is (C) 1 Area of flag \(=\frac12\times\) Base \(\times\) Height \(=\frac12\times(2+\sqrt2)\times(2-\sqrt2)\) \(=\frac{4-2}2\) = 1 square units
Correct option is D) 361
Correct option is A) 32
Correct option is A) \(\frac{\sqrt3}{4}\)a2
