The area of a trapezium is 45 cm2
and the perpendicular distance
between its parallel sides is 5 cm. If the length of one of its parallel sides is
6cm, find the length of the other parallel side.

x=12

Step-by-step explanation:

A=(6+x)*5/2=45

so (6+x)*5=45*2=90

6+x=90/5

6+x=18

x=18-6

x=12

12 cm

Step-by-step explanation:

Area of trapezium

½ × (sum of // sides) × h

45 = ½(6 + x) × 5

6 + x = 18

x = 12

answer: 590

step-by-step explanation:

(x+3)(x+7)
