Question

The perimeter of a sector is 4times the radius of it.find the area of sector...

​

Answer 1

Answer:are of sector is R^2

Step-by-step explanation:

Let x be angle formed by radius

Perimeter of sector = 4R

R + R +(x÷360×2πR)=4R

x÷180×π=2

X=360/π

Are of sector=x/360×πR×R

360/π×π/360×R×R

=R square=R^2=R×R
