Question

find the perimeter of a rectangle with length 5m and breadth
0.25 decameter. find the perimeter​

Answer 1

Answer:

15m

Step-by-step explanation:

first we will convert all the measurements in metres .

so, 5m remains the same , but the 0.25 is converted to 2.5m

then the formula of rectangle will be =

length + breadth × 2

= 5+2.5×2

=7.5×2

=15

so it will be 15 m .

Answer 2

Answer:

1metre = 10decimeter

5 m = 50 decimeter .

Perimeter of rectangle = 2(l+b) = 2(50+0.25) = 2*50.25 = 100.5 dm²
