Answer: 110 square cm
=======================================================
Explanation:
All sides of a regular polygon are the same length. So the bottom side is also 8 cm.
Draw lines from the center to each vertex of the pentagon. Five triangles form. Each triangle has a base of 8 and a height of 5.5 (since all five triangles are congruent)
area of one triangle = 0.5*base*height = 0.5*8*5.5 = 22
area of five triangles = 5*(area of one triangle) = 5*22 = 110
Answer:
x (378) + y (378) =
Step-by-step explanation:
First i split 756.00 in half so basically what ever is multiplied by two to get 756 and i got 378. So since x = 3.00 and y = 2.00, it would come out to this:
3.00 x 378 = x (378) =
2.00 x 378 = y (378) =
So:
x (378) + y (378) =
im sorry if i got it wrong-

Answer:
<em>The area of the actual building lot is</em> 
Step-by-step explanation:
<u>Scaling</u>
The scaled rectangular building measures 7 feet by 5 feet. We know both magnitudes were scaled by a factor of 12, thus the real dimensions of the house to be built are 7*12=84 feet, and 5*12=60 feet.
The area of the actual building lot is calculated by:
