Answer 1

hiii

area of triangle

s = a+b+c/2

1/2(122+22+120) = 132

A = √s(s-a)(s-b)(s-c)

= √132(132-122)(132-22)(132-120)

= √132*10*110*12

= √1742400 ⇒13200

• area of small triangle

s = a+b+c/2

= 1/2(26)(22)(24) = 36

A = √s(s-a)(s-b)(s-c)

= √36(36-26)(36-22)(36-24)

= √36*10*14*12

= √60480 ⇒24√105

now the area of shaded region is big triangle area-small triangle area

⇒13200 - 24√105

⇒12954.073

Answer 2

The area of the shaded region is 1074.08cm^2.

Hope this helps
