N = 10*27 / 87 = 270/18 = 15
Area means to multiply, so 9.3x16.5=153.4 cm.
Answer:
Ooof
Step-by-step explanation:
First i got the area which is : A= a+b divided by 2 x height
=2.5+3.5 divided by 2 x 2= 6
Area = 6
To get the perimeter you just add all the sides together so: 3.5+2.5+2.5+2.5= 11
=50-(50*30%)
=50-(50*0.30)
=50-15
=$35
the new cost would be $35
