Question

find the height of the trapezium in which parallel sides are 2 5cm and 10 cm and non parallel sides are 14cm and 14cm
​

Answer 1

Answer:

I don't know

Step-by-step explanation:

sorry but

area of trapezium = 1/2*(sum of parallel base)

*height

Answer 2

Answer:

√159.75 centimetres.

• Divide the trapezium into a rectangle and a triangle.
• The dimensions of the square will be 14cm x 2.5cm.
• The length of the hypotenuse of the triangle is given as 14cm.
• The base length is (10cm - 2.5cm) = 7.5cm.
• Therefore the height of the trapezium between the two parallel sides can be calculated using Pythagoras' theorem: (14 x 14 cm^2 - 7.5 x 7.5 cm^2)
• Which is equivalent to 196 sq. cm - 56.25 sq. cm.
• Then find the square root of 159.75.
