How do you find the total surface area of a 3-D composite figure? Do you subtract one base from one of the figures or both of it

s bases?

What does the shape look like?
Ok, so say you are calculating the surface area of the shape in the image below.
You would calculate the area of both shapes (the vertical box and the horizontal one), then subtract the area of the left face of the left rectangle (it is 10x20). That way, you are subtracting the area from the tall box. Make sure when you calculate the area of the short box that you don't include the left face (which is non-existent because it is attached to the tall box). If this is still really confusing (don't blame you if it is!!), let me know and I will walk through and example with you. Hope this helps!!

Answer:

Adults= 110

Children= 340

Step-by-step explanation:

Given data

let adults be x

and children be y

x+y= 450----------1

2x+y=680---------2

from 1

x= 450-y

put this in 2

2(450-y)=680

900-2y=680

900-680=2y

220=2y

y= 220/2

y= 110

x+110= 450

x= 450-110

x=340

Will give brainliest please help ASAP
marissa [1.9K]

Answer: 1) If we talk about whole numbers then we should choose only square numbers that could be the area of square so that if we want to find its  side so we a can find its square root i.e. side.

2) We can find the square root of the area of the given square to find the side length of the square.

3) No , it is not possible to find a side length that would be perfect for a square with an area of 45 square units because if we find its side we need to find its square root i.e.

side=\sqrt{45}=\sqrt{3\times3\times5}=3 \sqrt{5}................>which is irrational and √5=2.236

∴side=3×2.236=6.708 unit ......> which is not accurate we need to take approx value of it to get the side length of the square.
