Question

find the altitude of a trapizium, the sum of length of whose base is 6.5cm and whose area is 26cm^2​

Answer 1

Answer:

Let us consider the altitude of a trapezium as h

so the sum of lengths of parallel sides are 6.5cm

area=26cm²

we know area of trapezium=1/2 h(a+b)

1/2 h(6.5) =26

h(6.5) =26*2/1

h(6.5) =52

h=52/6.5

h=8cm

so altitude of a trapezium is 8cm

Answer 2

area of trapezium =1/2h(a+b)

1/2×h(6.5)=26

or,h=26×2/6.5

or,h=8

height or altitude =8cm
