you need to multiply the sides.
The surface area of a cube with sides of 4 cm is 6*42 square cm = 96 sq cm. The surface area of a cube with sides of 2 units is 6*22 square units = 24 sq units.
24 cm. sq.
A circle with radius 2.326 cm (approx) Various ellipses. A rectangle with sides 1 cm and 17 cm or with 2 cm and 8.5 cm or 3 cm and 5.667 cm etc or many other regular and irregular shapes.
This is a cuboid so it has six sides. The surface area is the sum of the areas of the sides. Opposite sides are the same. So we have: 2 sides of area 8 x 9 centimetres squared 2 sides of area 8 x 5 centimetres squared 2 sides of area 9 x 5 centimetres squared That's a total of 314 centimetres squared.
you need to multiply the sides.
That depends not only on the shape, but on how large it is. Any type of figure can be scaled so that it has any desired perimeter.Examples:A triangle with sides 1 cm, 2 cm, 6 cmA triangle with sides 1 cm, 2 cm, 5 cmA triangle with sides 2 cm, 3 cm, 4 cmA nonagon (more correctly an enneagon) with all sides 1 cm
A square with a side length of 2 cm has an area of 4 square cm
The surface area of a cube with sides of 4 cm is 6*42 square cm = 96 sq cm. The surface area of a cube with sides of 2 units is 6*22 square units = 24 sq units.
24 cm. sq.
Assuming that the shape is triangular, the area is approx 1139 cm^2.
4cm2
Any shape you want as long as the area within its boundary is 6cm2.examples:a triangle of base 6 cm and height 2 cm;a rectangle 2cm by 3 cm;an L shaped hexagon with sides 5cm, 2cm, 1cm, 1cm, 4cm, 1cm;circle of radius approx 1.382 cm;
2*2 = 4 square cm
A circle with radius 2.326 cm (approx) Various ellipses. A rectangle with sides 1 cm and 17 cm or with 2 cm and 8.5 cm or 3 cm and 5.667 cm etc or many other regular and irregular shapes.
The area of a square is (side)2. Since side = 7 cm, then area = (7 cm)2 = 49 cm2 [square centimeters].
The formula for the area of a trapezoid is (sum of lengths of parallel sides)/2 x perpendicular height. Assuming the measurements given are the parallel sides and the perpendicular height the area would be (4+5)/2 x 3 = 13.5 square cm.
