Question

Find the area and perimeter of a rectangle whose length is 4m and breadth is 100cm. ​

Answer 1

$\boxed{\boxed{\underline{\huge{\bold{\green{\mathfrak{Answer}}}}}}}$

4m=400cm

Then perimeter of rectangle is

$= 2(100 + 400)cm$

$\pink{1000cm}$

and area is

$= (100 \times 400)cm {}^{2} = 40000cm {}^{2}$

Answer 2

Answer:

Area of the rectangle =l×b

Given l=4m=400cm

b=100cm

Therefore, ar=l×b

400×100

=40000cm/sq...

Perimeter of a rect. =2(l+b)

=2(400+100)

=2(500)

=1000cm or 10m..
