Question:
The perimeter of a trapezium is 52 cm and its each non-parallel side is equal to 10 cm with its height 8 cm. Its area is
(a) 124 cm2
(b) 118 cm2
(c) 128 cm2
(d) 112 cm2
Solution:
Explanation:
Given:
The perimeter of a trapezium = 52 cm
The sum of its parallel sides = 52 – (10+10) = 32 cm
We know that, the area of a trapezium = (1/2) (a+b) h
A = (1/2) (32) (8)
A = 128 cm2
