perimeter of rectangle = 2(l+b)
150 = 2(45+b)
150= 90+b
90+b=150
b=150-90
b=60
breadth =60
150 = 2(45+b)
150= 90+b
90+b=150
b=150-90
b=60
breadth =60
LegendLui008:
wrong answer bro
when u r multiplying with 2 then it becomes 2b but u wrote only b
therefore 2b=60 and b=30
ok
i forgot to multiply b

2 (l+b)= 150 cm
l+b= 75cm
45+b=75 cm
b=30 cm
area= l×b
a=45×30
a=1350cm square
hope it helps @lui
l+b= 75cm
45+b=75 cm
b=30 cm
area= l×b
a=45×30
a=1350cm square
hope it helps @lui
but 45 × 30 =1350
