What is the area of this figure?

Area of a square(A) is given by:

, where s is the side of the square.

Area of a triangle(A') is given by:

From the given figure:

Labelled the diagram shown below.

In a triangle ABC:

BC = 5 cm and FA =4 cm

then;

Substitute the given values we have;

Now, find the area of square BCDE:

Side of the square BCDE (s)= 5 cm

then;

Then the area of the given composite figure :

Therefore, the area of the given figure is,

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
