A rectangular prism as 6 sides, 2 of each dimensions.
So this has 2 sides that are 5 x 5
2 sides that are 10 x 5
and 2 sides that are 10 x 5
Find the area of each, multiply by 2 then add them all together:
5 x 5 = 25
10 x 5 = 50
10 x 5 = 50
(25 + 50 + 50) x 2 = 250 m²
Answer : $757
explanation: 57.75 + 9.50 = 67.25
67.25/757
Y=x^2-3 for the third picture
A=32, B=32, C=148, D=148
A parallelogram has 2 sets of equal angles and the total sum of all angles is equal to 360
Angles A,B are 32, to work out CD add angles AB then subtract that from 360
=360-64
=296
To work out each angle (CB) divide that by 2, therefore C and D are 148
HOPE THIS HELPS
The answer is b. 9pi because 3^2xpi=9pi.
