we know that
The volume of a rectangular prism is equal to
-----> equation A
where
L is the length
W is the width
H is the height
we know that
-----> equation B
----> equation C
substitute equation B and equation C in equation A
Apply distributive property
Answer:
339.36 cm^2
Step-by-step explanation:
14*12.12=169.68
169.68/2=84.84
84.84= the area of one triangle
(84.84)4=339.36
I'm pretty sure, but check my math if it's wrong
Answer: 141.3
Step-by-step explanation:
I got it correct
Answer:
x = 45
Step-by-step explanation:
Corresponding sides of similar triangles will be in same ratio.
Cross multiply
x*28 = 20*(x+18) {Use distributive method}
28x = 20x + 360
28x - 20x = 360
8x = 360
x = 360/8
x = 45
