Question

please answer...... quadratic equation

Answer 1

★Perimeter of rectangle = 180m
★2(l + b) = 180
★2(x+b) = 180
★x+b= 90
★b= 90-x

★Area of rectangle = ★1800m²
★l*b= 1800m²
★x*(90-x) = 1800
★90x-x²= 1800
★x(90-x)= 1800

If 90-x= 1800
★Then
★x= 1800+90
★x= 1890m

★b= 90-x
★b= 90-1890
★b= -1800

Answer 2

so the lenght will be 60m and breadth will be 30m
hope it helps : )
