Answer:
Area = 100 cm²
Explanation:
A trapezium whose parallel sides are of length a and b, and the perpendicular distance between them is h has an area given by the formula
1/2 (a+b)h
In this question, the figure actually comprises of two trapezium which
parallel sides are 18cm and 7cm and height = 4cm
So, area of this figure = 2(1/2 (a+b)h) = (a+b)h
(a+b)h
= (18 + 7)*4
= 100 cm²
