Question

find the sum of the length of base of a Trapezium whose altitude is 17 cm and whose area 0.85 metre square​

Answer 1

Answer:

Area of trapezium = 1/2 (sum of parallel sides )×(distance between parallel sides)

=0.85m² = 1/2× sum of parallel sides× (0.17m)

=sum of parallel sides = 2×0.85m²/0.17m=10m

therefore 10m is the answer
