Question

A square of a area 9 sq.units is cut along its diagonal to form four triangles and these are arranged on another square of 9 sq.units to form a larger square.Then the area of the larger square is

• A. 81 sq.units
• B. 18 sq.units
• C. 27 sq.units
• D. 3 sq.units

Answer 1

The correct option is B

18 sq.units

If a square of a area 9 sq.units is cut along its diagonal as four triangles and these are arranged on another square of 9 sq.units to form a larger square,

Then the area of the larger square is double the area of the original square.

Hence, the area of the larger square = 2 x 9 = 18 sq.units
