square millimeters

107 square millimeters

Step-by-step explanation:

You can make this problem easier by splitting this into pieces you already know how to solve. So, you can draw a line down the middle to get 2 rectangles whose formula are Length X Width. Now, use the side lengths 5x7=35 and 8x9=72.

Add the 2 area of rectangles together to get 107 which is your total area.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
