Question

The area of an equilateral triangle DRS is 144 sq. cm. If P is the centre of the circle, find the area of quadrilateral DRPS in the given figure.

Answer 1

first find the length of the side of the of the equilateral triangle

Answer 2

a=6.

Answer 3

so radius =6

Answer 4

nope, Triangle DRS is equilateral
its area is 144 cm ^2
now, area of a triangle is given by A=b*h/2
So...the height of an equilateral triangle is given by an expression coming from pitagoras' theorem and there you calculate the side RS measure.

Answer 5

sorry .i thought prs is equilateral

Answer 6

2 sqrt(18)
