Question

Cut out a square of side 7 centimetres and another of side 3 centimetres. Cut the larger square suitably and join with the smaller square to make one large square.

What is the area of this square?​

Answer 1

Answer:

Area of new square is 49cm².

Step-by-step explanation:

Area of larger square = (7)² = 49 cm²

Area of smaller square = (3)² = 9cm²

We cut a 9cm² square from center of 49cm² square so we get a track of area = 49-9 = 40cm²

Thus area of new square is 40+9 = 49cm²
