Question

Find the area of the rectangle whose length is 4 Times of it's breath where breath is 3a unit​

Answer 1

${\huge{\bold{\underline{Answer:-}}}}$

Let length = 4 × 3a = 12a

breadth = 3a

Area = length*breadth

12a × 3a

36a

Answer 2

b=3a units

l=4×b

l=4×3a

l=12a units

area = l×b

area=12a×3a=36a² units
