Answer 1

Answer:

$A_{total} = 25\ ft^2$

Step-by-step explanation:

Step 1:  Determine the area of the square

$A = s^2$

$A = (3\ ft)^2$

$A = 9\ ft^2$

Step 2:  Split the top figure into a square and triangle

Determine the area of the rectangle

$A = l * w$

$A = (7\ ft - 3\ ft) * (5\ ft - 2\ ft)$

$A = (4\ ft) * (3\ ft)$

$A = 12\ ft^2$

Determine the area of the triangle

$A = \frac{b * h}{2}$

$A = \frac{\frac{7\ ft - 3\ ft}{2} * (5\ ft - 3\ ft)}{2}$

$A=\frac{2\ ft * 2\ ft}{2}$

$A = \frac{4\ ft^2}{2}$

$A = 2\ ft^2$

Since there are two right triangles in the triangle that we have we multiply the area that we got by 2 to get the total area.

$A_{triangle} = 2\ ft^2*2$

$A_{triangle} = 4\ ft^2$

Step 3:  Determine the total area

$A_{total} = 9\ ft^2 + 12\ ft^2 + 4\ ft^2$

$A_{total} = 25\ ft^2$

Answer:  $A_{total} = 25\ ft^2$
