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:
The area of this parallelogram is 
Step-by-step explanation:
The formula for working out the area of a parallelogram is : 
To work out the area you would multiply the base of 11 by the height of 4, this gives you 44 meters squared. This is because a identical parallelogram and a rectangle would have the same area.
1) Multiply 11 by 4.
This is the order from smallest to greatest: -10,-5,0,5,10
