Answer 1

Answer:

$\rm\displaystyle \: A _{ \text{ total}} = 212$

Step-by-step explanation:

Prefer the attachment

so we have 3 rectangle

recall that,

$\displaystyle \: A _{ \text{ rect}} = l \times w$

rectangle-1:

the width of the rectangle is 10m

and the length is 12+5=17m

so the area is

$\displaystyle \: A _{ \text{ rect - 1}} = 17 \times 10$

$\displaystyle \: A _{ \text{ rect - 1}} =170 \: {m}^{2}$

rectangle-2:

the length is 9 m

the width is 3 m

so the area is

$\displaystyle \: A _{ \text{ rect - 2}} = 9 \times3$

$\displaystyle \: A _{ \text{ rect - 2}} = 27 \: {m}^{2}$

rectangle-3:

the length is 5m

the width is 3m

so the area is

$\displaystyle \: A _{ \text{ rect - 3}} = 5 \times 3$

$\displaystyle \: A _{ \text{ rect - 3}} = 15 {m}^{2}$

total area:

$\rm\displaystyle \: A _{ \text{ total}} =170 \: {m}^{2} + {27m}^{2} + {15m}^{2}$

$\rm\displaystyle \: A _{ \text{ total}} = 212 {m}^{2}$
