Question

two adjacent sides of a rectangle are (7psquae -3pq+r) nad(5pq-4psquare). find its perimeter​

Answer 1

refer the attachment for the answer

Answer 2

Step-by-step explanation:

length =( 7p² - 3pq + r ) units

breadth =( - 4p² + 5pq ) units

Perimeter = 2 ( l+b)

= 2 [ (7p² - 3pq + r) + ( -4p² + 5pq) ]

= 2( 7p² - 4p² - 3pq + 5pq + r)

= 2( 3p² + 2pq + r)

= (6p² + 4pq + 2r) units
