Question

find the perimeter and area of a rectangle whose length is 1 m 25 cm and breadth is 80 CM

Answer 1

hey user
Given length=1m,25cm=125cm
breadth=80cm
perimeter of rectangle =2(l+b)
=2(125+80)
perimeter=2(205)=410cm
Area of rectangle=l×b=125×80=10000cm^2
Hope it helps

Answer 2

UILength of Rectangle = 1 m 25 cm
= 100 cm + 25 cm = 125 cm

Breadth = 80 cm

Area of rectangle = 125 × 80
= 10000 cm²

We know that

1000 cm ² = 1 m²

So 10000 cm ² = 10 m²

Thus Area of rectangle = 10 m²

The Perimeter = 2(l+b)

= 2( 125 + 80) cm

= 2 ( 205)

= 410 cm

= 4.1 m
