So,the area of triangle is 26.832 cm^2...
Verified answer
Answer:
26.83 cm²
Step-by-step explanation:
According to the condition:-
Slide of the triangle= 7 cm
Base of the triangle= 9 cm
Side of the triangle= 14 cm
Let the slide be 'a', base be 'b' and side be 'c'
Using the formulas
A= √s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c /2
Solving for A
A=1/4√﹣a⁴+2(ab)²+2(ac)²﹣b⁴+2(bc)²﹣c⁴
=1/4·√﹣7⁴+2·(7·9)²+2·(7·14)²﹣9⁴+2·(9·14)²-14⁴
≈26.83282cm²
