from a rectangular glass 2m by 3.5m , a square of maximum size has been cut. what will be the shape and size of the leftover glass? The edges of both the pieces are smoothened. What will be the cost of smmothening its edges at the rate of rupees 25 per metre?
Answers
Answer:
Area of class = length×breadth
= 2×3.5m
= 7 m square
let's assume maximum side of a square = 2 m
Area of square = side × side
= 2×2 = 4 m square
The left over size of glass = area of glass - area of square
(7-4) m square
3 m square
then, the leftover size of Glass 3 m square
the cost of smoothening its edge at the rate of rupees 25 per metre = 3×25 = 75 m square
hence the cost of smoothing its h at the rate of rupees 25 per metre is 75 metre square
