Leia cuts congruent triangular patches with an area of 45 square centimeters from the rectangle the fabric that is 18 cm long and 10 cm wide how many other patches can cut from the 32 pieces up the fabric

We first have to find the area of the rectangular fabric:
 A = (18) * (10) = 180cm ^ 2
 The number of triangular patches cut from the fabric is:
 n = (180) / (45) = 4
 As there are 32 pieces of fabric then:
 n '= 4 * (32) = 128
 
 She cans cut from the 32 pieces up the fabric:
 128 triangular patches with an area of 45 square centimeters
