A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm.
The area of a square with sides of length 7 mm: 7 millimeters times 7 millimeters are 49 square millimeters.
A triangle with side a: 7, side b: 7, and side c: 7 cm has an area of 21.22 square cm.
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
Let the shortest side be x cm, so that the longest side is 2x cm, and the third side is x + 7 cm. Since the perimeter of the triangle is 39 cm we have:x + 2x + x + 7 = 394x = 32x = 8Thus, the lengths of the sides are 8 cm, 15 cm, and 16 cm.
