It is the lateral area (which is 1/2 the perimeter multiplied by the slant height), plus the area of the base.

The lateral area is 188.5 m2

1/2 times the perimeter of the base times slant height

Lateral Area is the area of the sides of a solid, not including base.

SA = BA + 1/2 ps SA = BA + LA

It is the lateral area (which is 1/2 the perimeter multiplied by the slant height), plus the area of the base.

Total surface area= 1/2 times the perimeter of the base times the slant height plus the area of the base Lateral surface area= 1/2 times the perimeter times the slant height

(1/2 B)h another way is Lateral area + base area. Lateral area is 1/2 perimeter*slant height. You use this if you dont know the height but know the slant. or if you just like to do it this way

The lateral area is 188.5 m2

72 cm square.

The surface area is the area of the base plus the area of the slanted sides:SA = ba + lala = ps→SA = ba + ps

The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.

SA=BA+LA SA=BA+1/2ps

No, the slant height is the from the top vertex to the base of the base of the pyramid, it forms a 90 degree angle with the base and slant height. The lateral edge is literally the lateral (side) edge.

Lateral Area is the area of the sides of a solid, not including base.

1/2 times the perimeter of the base times slant height
