Question

In the given figure, ABCD and ABFE are parallelograms and ar(quadrilateral EABC) = 17cm² and ar(parallelogram ABCD) = 25cm². Find ar(∆BCF)

Answer 1

here is your answer

Answer 2

Area of triangle BCF is 8 cm².

Step-by-step explanation:

Given:

ABCD and ABFE are parallelograms

Ar(EABC) = 17cm² and

Ar(ABFE) = 25cm².

To Find

Ar(∆BCF)= ?

Solution:

$\textrm{Area of triangle BCF}=\textrm{Area of Parallelogram ABFE}-\textrm{Area of quadrilateral ABCE}$

Substituting the value we get

$\textrm{Area of triangle BCF}=25-17=8\ cm^{2}$

Area of triangle BCF is 8 cm².
