Perimeter of the square:
P = 4a
P = 4 × 7 cm
P = 28 cm
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.
The perimeter is 7 cm
the perimeter of a square that has a side length of 7 cm is........28cm squared
The area of a square is (side)2. Since side = 7 cm, then area = (7 cm)2 = 49 cm2 [square centimeters].
Perimeter =7+7+10+10 = 34 cm
28cm (4 sides x 7 = 28)
Its 4 equal sides are 7 cm and so 4*7 = 28 cm which is its perimeter
If it has a 28 cm perimeter, its sides are length 28/4 = 7. So, the area would be 7 x 7 = 49 cm2.
The area of square is the square of one of its sides, which are all equal. To find the value of a side, take the square root of the area. In this case the square root of 49cm2 is 7cm. The perimeter is the sum of all four sides of the square, so the perimeter of a square with an area of 49cm2 is 7+7+7+7 = 28, or 4x7 = 28.
If the area of a square is 49 square centimeters, the length of each of its sides are: 7 cm.
You measure the sides of the shape you are finding the perimetre of and then add together the measurements. Then you have your answer. eg: 8cm x 7cm x 3cm x 5cm 8+7+3+5=23 answer is 23cm
The term "perimeter" refers to the total length of the sides of a geometric shape. If you're asking about a shape with a perimeter of 7 cm, it means the sum of all its sides equals 7 cm. For example, a square with each side measuring approximately 1.75 cm would have a perimeter of 7 cm.
7 cm x 3 sides = 21 cm perimeter.
