Its 4 equal sides are 7 cm and so 4*7 = 28 cm which is its perimeter

12.25 square cm

perimeter of a circle = circumference = pi x diameter perimeter = 3.1416 x 12 = 37.7 cm

The area is 0.5*24*10 = 120 square cm. The third side is sqrt(24^2 + 10^2) = 26 cm. So the perimeter is 60 cm.

None. A 7-sided figure is a "heptagon." An 8-sided figure is an "octogon."

It is: 4*8 = 32 cm

the square is 4 cm per side, so area is 4x4=16 cm2

A regular hexagon has 6 sides of equal length ("hex" means six). The perimeter is just the length of all the sides added up. So, Perimeter = 6 x 7 = 42 cm

The perimeter is pi*r + 2r = 92.6 cm

2*l+2*22/7*r

The answer is 40 (cm?). 6 + 6 (both sides) +14+14= 40
