Perimeter of a sector =l+2 r=4 r.

Q. The area of a sector whose perimeter is four times its radius ( $r$ units) is:

$r$ sq. units.

$r^{4}$ sq. units.

$r^{2}$ sq. units.

$\frac{r ^{2}}{2}$ sq. units.

Perimeter of a sector $= l + 2 r = 4 r$ .

Q. The area of a sector whose perimeter is four times its radius ( r units) is:

r​ sq. units.

r4 sq. units.

r2 sq. units.

2r2​ sq. units.

Perimeter of a sector =l+2r=4r.
