Question

Need help on geometry

Answer 1

Aa = 13*20 = 260 sqm

for Area b;
sides must be 5 and (20-4)=16
So;
Ab = 16*5 = 80 sqm

for Area c;
sides must be 13 and 3
So;
Ac = 3 * 13 = 39

Total area of the figure is Aa + Ab + Ac = 260 + 80 +39 = 379 sq.m

Answer 2

We can subdivide the figure in 3 rectangles A, B, and C, then we can find the area of each rectangle and add all the areas together to find the total area of the picture.

`A_(A)=(20)(13)=260`

`A_(B)=(16)(5)=80`

`A_(C)=(3)(13)=39`


`A_(total)=260+80+39=379`

We can conclude that the area of the figure is 379 square units.
