Given perimeter = 51.8mAnd length = 16.5m
and we know perimeter = 2(l + b)
This means perimeter = 2(16.5 + b)
But perimeter = 51.8m
So we can write
=> 2(16.5 + b) = 51.8m
=> 16.5 + b = 51.8/2
=> 16.5 + b = 25.9
=> b = 25.9 - 16.5
=> b = 9.4
Now we have to find the area.
What's the formula for area?
Yes, it's Length × Breadth
Hence, area of given rectangle
= length × breadth
= 16.5 × 9.4
=> 155.1m²
Hope it helps dear friend ☺️✌️
Verified answer
P=51.8m
l=16.5m
b=?
A=?
Perimeter of rectangle=2(l+b)
51.8=2(16.5+b)
=(2×16.5)+(2×b)
=33+2b
51.8 -33=2b
18.8=2b
b=18.8÷2
b=9.4m
Area=l×b
=16.5×9.4
=155.1m²
Hope it helps
