The area of the trapezoid is equal to half
the product of the height and the sum of

the lengths of the parallel sides. Let L be
the area of the trapezoid having the height
t and the length of the parallel sides a1 and

a2, so L = t x ( a1 +a2 )

Geography.Estimate the area of the area indicated by the area of the
trapezoid in the picture below!!

Solution:

Is known : t = 51

a1 = 85

a2 = 107

Asked : Area of trapezoid

Answer : :

L = t x ( a1 +a2 ) The formula for the area of a trapezoid

= x 51 x (85+107) = 4896

So the area of Samarinda is approximately 4896 km 2
