Answer:
20 blue beads........20 black beads
First of all, let's remember the formula for calculating area. <em><u>Length times width equals area.</u></em> (lxw=a)
Now that we have the formula. Let's take the length (8 cm) and the width (6 cm) and add 1 cm to each of them.
Length: 8+1=9.
Width: 6+1=7.
Now, let's apply the formula for area.
9 x 7 = 63
Now that we've found the area is 63 cm, let's find the perimeter. To find the perimeter of a rectangle, we must multiply the length by 2 and the width by 2, then we add the two numbers. In this case, here's what we'll do:
9 x 2 = 18
7 x 2 = 14
18 + 14 = 32
Now we have the area and perimeter.
Final answer(s):
Area = 63 cm.
Perimeter = 32 cm.
