Question

the perimeter of a rectangle is 130 M and its breadth is 30 M find its length and area find the cost of making it if 1 metre square cost rupees 1.50

Answer 1

Length is 35m
Area is 1050m^2
Amd cost is ₹1575

Answer 2

the perimeter of rectangle is 130 M. and it's given that the breadth is 30 M.
perimeter of rectangle= 2(l+b)
130=2(l+30)
130=2l+60
130-60=2l
l=70
so the length is 70 M.

area of rectangle =l×b
=(70×30)M²
=2100 M²

The cost of making that rectangle=(2100×1.50)rupees
=3150 rupees
