the parallel sides of a trapezium are 7.5cm and 3.9cm ; and other sides are each 2.6cm. Find its area.
Answers
Area of Trapezium= 10.69 cm²
Step-by-step explanation:
the parallel sides of a trapezium are 7.5cm and 3.9cm
other sides are each 2.6cm
=> isosceles trapezium
if we draw perpendicular fro vertex of 3.9 cm side to 7.5 cm side
Space between Perpendicauler Drawn & nearest vetex of 7.5 cm woould be
= (7.5 - 3.9)/2
= 1.8 cm
Perpendicular height Would be = √ 2.6² - 1.8²
= √3.52
= 1.876 cm
Area of Trapezium= (1/2)(7.5 + 3.9)(1.876)
= 10.69 cm²
