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.
