Leia cuts congruent triangular patches with an area of 45 sq. cm. From a rectangular piece of fabric that is 18 cm long and 10 cm wide. How many patches can she cut out from 32 pieces of fabric? Explain the whole thing please including the area of a triangle formula

So each Rectangular piece of fabric is 18cm  by 10cm so the area of the rectangular pieces of fabric are 180 but there is 32 of them so 180 x 32 =5760

So that means you have 5760 sq. cm of rectangle fabric

5760 / 45 = 128

You could have 128 triangular patches 

Hope this helps :)
