Answer: 53.2
Step-by-step explanation:
Using pythagorean theorem, a^2 + b^2 = c^2
40^2 + 35^2 = sqrt of 2825
which is 53.15
rounded up to nearest tenth is 53.2
we know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
So
1) 

2) 

3) 

therefore
the answer is

Answer:
18ft²
Step-by-step explanation:
V volume pyramid = 1/3× base area × height
V = 1/3 × B × h
24 ft³ = 1/3(12ft²)(6ft)
when V =54 ft³ h= 9ft B =?
V=1/3Bh
B=V3/h
B=(54×3)/9
B=6×3
B=18 ft²
Starting with:

First, the difference of 2 squares shows that

Sub that in and multiply both sides by

:

This easily simplifies to
