Question

which rectangle has the greater area one which is 12m by 9 m or one which is 10m by 11m

Answer 1

lb=12*9=108m^2
LB=10*11=110m^2

=>the rectangle which is 11m by 10m has a greater area by 2m^2

Answer 2

let the one rectangle be A which is 12m by 9m

and other be B which is 10m by 11m


now,
the area of rectangle A = l× b
=(12 × 9) m
=108meter square
then,
the area of rectangleB .=l×b
=(10× 11)m
= 110 meter square
108<110
i.e.
area of rectangle A is smaller than of B

so,
the area of rectangle B which is 10m by 11m is greater....



Hope it is correct and will help u.....
