Question

Find the area of the parallel sides of a trapezium are 11cm by 15cm and the distance between them is 7cm

Answer 1

Step-by-step explanation:

The area of a trapezium = A = (a+b)h/2

Where, A = 84 cm², a = 11 cm, b = 13 cm, h = ?

Or, The area of a trapezium = (11+13)×h/2 = 84 cm²

Or, 24×h/2 = 84

Or, 24×h = 84×2

Or, h = 84×2/24

Or, h = 7 cm

Answer 2

Answer:

$91 \: cm^{2}$

Step-by-step explanation:

area of trapezium =1/2×(a+b)×h

= 1/2 ×(11+15)×7

= 1/2×26×7

= 13 ×7

=$91 \: cm^{2}$
