What is perimeter and area called in mathematics?

The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.


What is the area of a triangle that is 8 cm 13 cm 7 cm?

Oh, what a happy little triangle we have here! To find the area, we can use Heron's formula. First, we find the semi-perimeter by adding all three sides and dividing by 2. Then we plug the values into the formula: Area = √(s(s-a)(s-b)(s-c)), where s is the semi-perimeter, a, b, and c are the sides. Happy painting!
