(1) L=5m
b=?
area =15m²
find the perimeter and breadth
area of rectangle=l×b
15=5×b
b=15/5
b=3m
perimeter of rectangle=2(l+b)
=2(5+3)
=2(8)
= 16m²
(3)L=?
b=9.5cm
perimeter=24cm
find the area and length
perimeter of rectangle= 2(l+b)
24= 2(l+9.5)
24=2l+19
24-19=2l
5=2l
l=5/2
l= 2.5
area of rectangle=l×b
=2.5×9.5
=23.75
