That is so wrong!
Let the three sides be a, b and c and let s = (a+b+c)/2
then area = sqrt[s*(s-a)*(s-b)*(s-c)]
So here s = 14.5 cm and so area = sqrt(14.5*2.5*7.5*4.5) = sqrt(1223.4375)
= 34.98 sq cm (to 2 dp)
The area of a triangle = (base * height) / 2. So here, the area = 12 * 7 / 2 = 84/2 = 42 cm2.
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
Area 51.
A triangle with side a: 7, side b: 7, and side c: 5 cm has an area of 16.35 square cm.
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^
10cm x 7cm x 12cm =840 square cm3
What is the area of the triangle 10cm ,8cm and 6cm
The area of a triangle = (base * height) / 2. So here, the area = 12 * 7 / 2 = 84/2 = 42 cm2.
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
if it is a scalene triangle yes scalene triangle have no congruent sides and angles
70 square cm.
what is the perimeter of a rectangle that's 10cm x 7cm
The area defined by the above measurements is 70 square centimeters.
The area of triangle is : 42.0
Two sides of a triangle are not sufficient to determine its area.
Area 51.
No because the sum of the smaller sides must be greater than the longest side
