Teacher hint: use a scale drawing

Please need help i have a b in math

Answer 1

First of all, let's remember the formula for calculating area. Length times width equals area. (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.

Hope this explanation helped you out. :)
