Question

find the area of trapezium ABCD​

Answer 1

Answer:

92.5cm

Step-by-step explanation:

Consider the Shape ABCD as a square and consider the Shape BEC as a triangle. Now find the area of each shape:

1) Area of Square ABCD = Length x Breath

= 12cm x 5 cm

= 60cm

2) Finding Side EC using Pythagoras' Theorem

= √13²-12²

= 5cm

3) Area of Triangle BEC = ½ x Base x Height

= ½ x 5cm x 13cm

= 32.5cm

4) Adding Value 1) and 3) to get the Total Area

Therefore Total Area = 60cm + 32.5cm

= 92.5cm
