Step-by-step explanation:
By considering the word respectively,
L=3X²×2Y in meters
B=5XY²×2 in meters
AREA OF A RECTANGLE= L×B
ANSWER=3X²×2Y×5XY²×2
multiply the common numbers first or we say like terms altogether.
=3×2×5×2=60. do not multiply the squared number 2.
=X²×X= X³, because the bases are all the same in multiplication we add the exponents 2 and 1 although 1 is not written as an exponent at the second X
=Y×Y²=Y³
ANSWER= 60X³Y³ in sq.m
