Answer:
You need to get the Perimeter.
Perimeter is simply sum of all the sides.
so,
P = 75 + 75 + 48 + 48 = 246 cm
therefore, they need 246 cm long of lace.
Alternatively, Perimeter of Rectangle i given as a formula of:
P = 2(L+W)
so using this equation let's check if we will have the same answer as above
P = 2(L+W)
P = 2(75+48) = 246cm
so same answer!
TIP: Without memorizing formulas of Perimeter of different polygons, just think that Perimeter is simply adding up all the sides! Now you basically know all formula of Perimeter of any given polygon!
