Question

Find the sum of the trapezium,the bases of a trapezium whose altitude is 17cm and whose area is 0•85m

Answer 1

Step-by-step explanation:

0.85=1/2×(sum of ll sides)×h

0.85=1/2×(-----)×0.17

sum of ll sides=10m

Answer 2

Answer:

Step-by-step explanation: 1m=100cm

So'0.85m=0.85×100=85cm

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

85cm =1/2×17(a+b)

85×2/17 =a+b

10 cm=a+b
