Answer:
Step-by-step explanation:
Remark
This is a right angle triangle.
Proof
a^2 + b^2 = c^2
a = 3
b = 4
c = 5
3^2 + 4^2 = 5^2
9 + 16 = ? 25
25 = 25
Area
The 2 smaller legs are perpendicular to each other.
Area = 1/2 a * b
Area = 1/2 * 3 * 4
Area = 6
Is porque P-Q-R (QR) =3, I(PR)= 12 then find I (QR)
Answer:
3.5ft
Step-by-step explanation:
To calculate the volume of something, you need to know the formula. Length x width x height. You already know the width, and the height, so you need to find the length.
4ft x 6ft x 3.5ft = 84ft^3
