Find the area of the triangle

A- 1,432 yd2

B- 1,350 yd2

C- 2,425 yd2

D- 1,325 yd2

Help

Part 1)  

Part 2)

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

so

Part 2)

we know that

The area of triangle is given by the formula

we have

substitute

-232

step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
