Answer:
21√2 m
Step-by-step explanation:
AC = √AD²+CD²
= √21²+21²
=√2×21²
= 21√2 m
Answer:
Integers are any whole number negative or positive
Step-by-step explanation:
Well A.Given Information B. Postulates D.A Theorem That has already been proven Are all Right Except C.
The surface area of a shape is basically the sum of all the areas on a shape.
We’ve been given that the side is 17 mm.
An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.
Once we do that we get that the area of 1 square is 289.
Since there are 6 squares we need to multiply 289 by 6.
Therefore,
SA=1734mm^2
A=lw and A=bh are the same equation in terms of a square you just need to simply think of the swuare as standing up with bh and lw as laying down
they both work
