hiii,
PERIMETER = 2(L + B) = 47
=> 2(15 + B) = 47
=> 30 + 2B = 47
=> 2B = 47 - 30
=> 2B = 17
=> B = 17/ 2 = 8.5m
AREA = 15 × 8. 5 = 127.5 m^2
{B}Hope it helps you ,pls mark as brainliest answer{/B}......

Length =15m
Perimeter =2(l+b)=47
=l+b=47/2
=15+b=23.5
=b=23.5-15=8.5m
Area of rectangle = l*b
=15*8.5
=127.5m²
