The lateral area of the pyramid is half the product of the perimeter and the slant height.
A = (1/2)Ph
A = (1/2)*(4*40 ft)*(18 ft) = 1440 ft²
This is 14.4×(100 ft²), so is 14.4 squares. Since 3 bundles are needed for each square of roof, Lourdes needs 14.4×3 = 43.2 bundles.
Lourdes should buy 44 bundles of shingles to cover the roof.
_____
43 bundles is not enough.
Answer:
10cm
Step-by-step explanation:
Right angle triangle area= ab/2
GO IN REVERSE
24 x2= 48
48/8=6
now you have the 2 side you need to use Pythagoras
6^2+8^2=100
square root of 100=10cm
so the hypotenuse is 10 cm
25+15=40, so to find percent of voters for candidate B you do 25/40 multiplied by 100.
2104>2014
