Question

The perimeter of a triangle is (x ^ 2 * y + 10) units. One of the sides is of length (x ^ 2 * y - 4) units and another side is (3 - 2x ^ 2 * y) units. Find the length of the third side​

Answer 1

Answer:

Solution:-

Given:-

→Perimeter of triangle = (x²y + 10)

→First side of triangle (A) = (x²y -4)

→Second side of triangle (B) = (3 -2x²y)

To Find:-

→Length of third side (C).

Formula used:-

→Perimeter of triangle = A + B +C

Now,put all the values in the formula. We

get

→Perimeter of triangle = A +B+C

→(X²y +10) = (x²y - 4) + (3 -2x²y) +C

→(x²y + 10) - x²y -4) - (3-2x²y) = C

→x²y +10-x²y + 4 -3+2x²y = C

→10 +1+2x²y = C

→C = 11+ 2x²y
