Question

the area of the trapezium is
${210}cm^{2}$
and it's height is 5cm. if one of the parallel sides is 38cm, find the length of the other parallel sides
​

Answer 1

Step-by-step explanation:

area of trapezium= 1/2×(a+b)×h

=1/2×(38+b)×5

210=1/2×(38+b)×5

210×2/5=(38+b)

84=38+b

84-38=b

46=b

the other parallel side is 46cm
