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
It is: 20*7 = 140 square 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.
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
If the area of a square is 49 square centimeters, the length of each of its sides are: 7 cm.
7 cm x 3 sides = 21 cm perimeter.
A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm.
The area is the side x side = 49 side = 7cm ( sqrt of 49) perimeter is some of sides = 7 + 7 + 7 + 7 = 28 cm
