Question

From a rectangular glass 2 m by 3.5 m, a square of maximum size has been
will be the shape and size of the leftover glass?
The edges of both the pieces are smoothened. What will be the cost of smoothening its
edges at the rate of 25 per metre?
​

Answer 1

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
