Mathematics Question and Solution
Let a be the radius of the circle.
b²+2² = a²
b = √(a²-4) units.
c = 5+2
c = 7 units.
d = 3a units.
It implies;
Calculating a.
(3a)² = √(a²-4)²+7²
9a² = a²-4+49
8a² = 45
a = √(45/8)
a = 2.3717082451 units.
Again, a is the radius of the circle.
BD = 4a
BD = 4*2.3717082451
BD = 9.4868329805 units.
BD is the diagonal of a square.
It implies;
2e² = 9.4868329805²
e² = ½(90)
e² = 45 units.
Where e² is the area of the square.
