Question

leia cuts congruent triangular patches with a area of 45 square centimeters from a rectangular piece of fabric that is 18 centimeters

Answer 1

Let's assume that the rectangular piece is a square.
So first, we need to find the total area of the fabric.
Area = 18 * 18
Area = 324 cm^2

The area of a triangular patch is 45 cm^2.
So, there are
No. of patches = 324 / 45
No. of patches = 7.2

So, there are 7 triangular patches made from the whole fabric.
