a = 12 cm
b = 14 cm
h = 8 cm.
Compute the area. How many cm2?
You can use Heron's formula, which calculates the area of a triangle from the lengths of the three sides.
Let a,b,c=lengths of the three sides
s=(a+b+c)/2
Area of triangle
=sqrt(s(s-a)(s-b)(s-c))
Post your answer for a check if you wish.
I believe the figure is a trapezoid. I have misread it as a triangle (with given sides a, b and c).
The area of a trapezoid (trapezium) is
(a+b)h/2
=(12+14)*8/2
=104
To compute the area of a trapezoid, you can use the formula:
Area = (a + b) * h / 2
Let's substitute the given values into the formula to calculate the area:
Area = (12 cm + 14 cm) * 8 cm / 2
First, we can simplify the addition inside the parentheses:
Area = (26 cm) * 8 cm / 2
Next, let's multiply 26 cm by 8 cm:
Area = 208 cm² / 2
Finally, we divide 208 cm² by 2 to get the final result:
Area = 104 cm²
So, the area of the trapezoid is 104 cm².
To compute the area, we can use the formula for the area of a trapezoid:
Area = (a + b) * h / 2
Plugging in the given values:
Area = (12 cm + 14 cm) * 8 cm / 2
Now, let's simplify the equation:
Area = (26 cm) * 8 cm / 2
Area = 208 cm² / 2
Area = 104 cm²
Therefore, the area of the trapezoid is 104 cm².
