Question

Perimeter and areas formula of square,cube circle.triangle.sphere .rectangle.cone .and cube

Answer 1

Perimeter of square=4a^2 where a is side.
Area of square=a^3 where a is side.

Perimeter of cube=12*side
Area of cube=6a^2 where a is side.

Perimeter of circle= 2[tex] \pi ^2 [/tex]
Area of circle=$\pi r^2$

Perimeter of triangle=side+base+side.
Area of triangle=1/2*base *height.

Perimeter of sphere =No perimeter of sphere 
Area of sphere = 4$\pi$r^2.

Perimeter of rectangle=2(l+b)
Area of rectangle =l*b.

Perimeter of cone=2r+s=2r+Ф/360 * $\pi$r=2r(1+$\pi$Ф/360.
Area of cone=$\pi$rl.
