Answer 2

Answer:

$hello$

Find the areas of rectangles with the following pairs of monomials as their lengths and breadths respectively:

(p, q); (10m, 5n); (20x2, 5y2); (4x, 3x2);

(3mn, 4np)

Sol. We know that the area of a rectangle = l × b, where l = length and b = breadth.

Therefore, the areas of rectangles with pair of monomials (p, q); (10m, 5n); (20x2, 5y2);

(4x, 3x2) and (3mn, 4np) as their lengths and breadths are given by

p × q = pq

10m × 5n = (10 × 5) × (m × n) = 50mn

20x2 × 5y2 = (20 × 5) × (x2 × y2)

= 100x2y2

4x × 3x2 = (4 × 3) × (x × x2)

= 12x3

and, 3mn × 4np = (3 × 4) × (m × n × n ×)
