<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>
<em><u>Solution:</u></em>
The given pyramid has 3 lateral triangular side
The figure is attached below
Base of triangle = 12 unit
<em><u>Find the perpendicular</u></em>
By Pythagoras theorem
Therefore,
<em><u>Find the lateral surface area of 1 triangle</u></em>
<em><u>Thus, lateral surface area of 3 triangle is:</u></em>
3 x 48 = 144
Thus lateral area for the pyramid with the equilateral base is 144 square units
Formula- Area = L • W
So...
Length = 18 + 3
Width = 18 + 3
Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.
Length = 21
Width = 21
Now you’re gonna want to multiply 21 by itself.
21 • 21 = 21 + 420 = ?
Which leaves you with the final sum of...
Area = 441 yds.
Answer: Sheldon babysat for 6 hours on Saturday.
Step-by-step explanation:
Let x represent the number of hours that Sheldon babysat on Saturday.
He babysat for Saturday and Sunday. If Sheldon babysat for 8 hours on Sunday, it means that the total number of hours that he babysat during the weekend was
(8 + x) hours.
Seldon gets paid $4 per hour to baby sit his cousins. It means that the total amount that he earned during the weekend was 4(8 + x)
He made a total of $56. Therefore,
4(8 + x) = 56
8 + x = 56/4 = 14
x = 14 - 8
x = 6 hours
Answer:the answer will be 6
