Question

find the perimeter of a quadrilateral whose sides are 4a + 2b2, 8a - 7b2, "-5a" - 3b 2 and "-a" + 6b2

pls help :(

Answer 1

Answer:

As we know that the perimeter of a triangle is sum of length of all the sides. Hence,

Perimeter =2a+3b+b−a+4a−2b

⇒5a+2b.

Hence, this is the required answer.
