Question

A small square of side 2x is cut from the corner of a rectangle with a width of 10 centimeters and length of 20 centimeters. Write an expression in terms of x for the area of the remaining shape.

Answer 1

area of the square = side²

= (2x) ²

= 4x²

and the area of the rectangle= l×b

=20cm×10cm

= 200cm²

so, the remaining area = ar(rectangle)-ar(square)

= 200- 2x²

so, ur required equation is 200-2x²
