Question

Find the area of the trapezium whose parlell sides are of length 12 and 36 and each onon parlell sides are length 15cm​

Answer 1

Answer:

216 cm

Step-by-step explanation:

Construct a line parallel to the non parallel side such that the given figure is a parallelogram and the rest of the figure will be a triangle with sides 15, 15 and 24 cm respectively. Calculate the area of the triangle by herons formula. Then equate the area in the formula 1/2*b*h and calculate the height of the trapezium and the area of trapezium would be

1/2*(12+36)*9=216cm
