Question

10.The area of trapezium of height 3 cm is 12 cm .If one of the parallel sides is 3 cm,

what is the length of other side?​

Answer 1

Answer:

Area= 12cm sq

height= 3cm

one of the parallel side= 3cm

let the other parallel side be xcm

B/Q:

• 1/2 × (SUM OF PARALLEL SIDES) × HEIGHT= AREA
• 1/2 × (3+X) × 3= 12
• (3+X) ×3 = 12×2
• 9+ 3X = 24
• 3X= 24- 9
• 3X= 15
• X= 15/3
• X= 5cm

Therefore, the length of the other side is 5cm
