Question

Jasmin decided to make a 45 cm square pillow for her study chair. One piece of fabric will be required for the front of the pillow, and one for the back. Each piece of fabric will need an extra 1 cm on all edges for the front and back to be sewn together. What area of fabric will Jasmin need to make the pillow?

the answer is 4418cm, but I don't know how to work the question out. pls help ​

Answer 1

4418 cm²

Explanation:

The side of the initial square is 45 cm

Since each edge is increased by 1 cm, the new square has a side of:

45 + 1 + 1 = 47 cm

Ar of square= side²

= 47²

= 2209 cm²

Since 2 squares are required for the pillow, the total fabic needed is:

2209 * 2

= 4418 cm²
