an someone please help me with this math homework please am in 7th grade https://ibb.co/chnVyG4 and when your done answer the question here is the answer key for the question that I gave you https://ibb.co/x7vXJnp

Answer 1

we want to find the total surface area now

we have 2 squares with sides of 10

and we have 4 rectangles that have a width of 8 and a length of 10

Answer 2

what is the area of the square?

area of square = side * side

so if the side is 10

what is the area?

Answer 3

100

Answer 4

Good!

Now what about the rectangles?

Area of rectangle = length * width

the length is 10
the width is 8

area = ?

Answer 5

80

Answer 6

Excellent!!

So now we want to find the total surface area

that means we add up the area of each shape

total surface area = square + square + rectangle + rectangle + rectangle + rectangle

total surface area = 100 + 100 + 80 + 80 + 80 + 80

total surface area = ??

Answer 7

520

Answer 8

and that's your final answer

so whatever letter is on this slide goes above 520
