Question

Find the areas of the rectangles with the
following pairs of monomials as their
lengths and breadths respectively.
b. (10p, 6q)
d. (2pq, 4rs)
a. (2a, 3b)
c. (2x²,3y²)
e. (20x²,5y²)

Answer 1

Answer:

Area of rectangle=l×b

a.(2a,3b)

area=2a×3b

area=6ab

b.(10p,6q)

area=10p×6q

area=60pq

c.(2x^2,3y^2)

area=2x^2×3y^2

area=6x^2y^2

d.(2pq,4rs)

area=2pq×4rs

area=8pqrs

e.(20x^2,5y^2)

area=20x^2×5y^2

area=100x^2y^2
