triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle
a^2 + b^2 = hypotenuse squared
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 =
18.5
add up the areas of the 2 triangles and rectangle
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the
square root of 702.25 which is
26.5
to get the perimeter
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
Answer:
where is the equation so that if people sees this they can help you solve it
Common ratio, r is found by dividing the next term by the previous term
r =
= -3
you can see this value is true for any consecutive pairs of terms
also, multiply by -3 to get the next term
1. H=4
W=8
2. L=27
W=21
1. 160÷5=32
1/2 of 8 is 4
8×4=32
I am default dancing right now
2. 2×6=12
96-12=84
84÷4=21
21+6=27 (the length)
21= (the Width)
