The area and height of the trapezium are 34 cm2 and 4 cm. One of its parallel side is 10 cm. Find the length of other parallel side. |
|
Answer» Let b cm. be the required length of parallel side. Area of trapezium = 1/2 x (Sum of parallel sides) x height ⇒ 34 = 1/2 x (10 + b) x 4 ⇒ 34 x 2 = (10 + b) x 4 ⇒ 68 = (10 + b) x 4 ⇒ 10 + b = 68/4 ⇒ 10 + b = 17 ⇒ b = 17 – 10 ⇒ b = 7 Hence, the length of another parallel side is 7 cm. |
