Area of triangle roof:

= 1/2 (3.5)(1.2)

= 2.1 m^2

Area of large rectangle:

= 3.5 x 2.5

= 8.75 m^2

Area of small rectangle (door):

= 1.5 x 2

= 3 m^2

Total area:

= 2.1 m^2 + 8.75 m^2 +

= 13.85 m^2

$\bf{1) \ x^4-61x^2+900=0 }$

Applying the factorization method, for example:

$\bf{ 0=(x^2)^2-61(x^2)+900=(x^2-36)(x^2-25)}$

$\bf{\\ &=(x+6)(x-6)(x+5)(x-5); }$

$\bf{ x_1=6 \quad x_2=-6 \quad \ \ \ x_3=5 \quad x_4=5 }$

$\bf{2) \ x^4-25x^2+144=0 }$

Applying the factorization method:

$\bf{0&=(x^2)^2-25(x^2)+144=(x^2-16)(x^2-9) }$

$\bf{ =(x-4)(x+4)(x-3)(x+3); }$

$\bf{ x_1=4 \quad x_2=-4 \quad x_3=3 \quad x_4=-3 }$
