Question

the length of a rectangular field is three times its breadth if the breadth of the rectangle is 3 whole 1/2 metre find the perimeter of the rectangle

Answer 1

Answer: 18m

Step-by-step explanation:

perimeter= all length + all breadth

breadth=3.5m

length=10.5m

perimeter=3.5+3.5+10.5+10.5=18m

Answer 2

Breadth =
$3 \frac{1}{2} m$
= 7/2 m
= 3.5 m

Length = 3 × 3.5 m
= 10.5 m

Perimeter of the rectangle = 2 (l + b)
= 2 (3.5 m + 10.5 m)
= 2 × 14 m
= 28 m
