Question

In her metalwork class, Anja cut a square of

tin, of edge 3.7 cm, from a larger square of
edge 6.3 cm. What area of tin was left?

Answer 1

Given:

Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.

To find:

The area of the remaining tin.

Solution:

Area of a square is:

`Area=a^2`

Where, a is the edge of the square.

Area of the smaller square is:

`A_1=(3.7)^2`

`A_1=13.69`

Area of the larger square is:

`A_2=(6.3)^2`

`A_2=39.69`

The area of the remaining tin is:

`A=A_2-A_1`

`A=39.69-13.69`

`A=26`

Therefore, the area of the remaining tin is 26 sq. cm.
