Answer:
13.60
Step-by-step explanation:
use Pythagoras theorem
it is c²=a²+b²
c is hypotenus which is the longest side of a right angle triangle
--->now just put 8 on a and 11 on b
this gives us
c²= 8²+11²
c²= under the root 185
c² = 13.60147051
nearest hundredth is 13.60
hope you understood :)
Answer:
x = 13.60
Step-by-step explanation:
since it is a right angled triangle , we can use pythagoras theorem ,
hypotenuse^2 = base^2 + perpendicular^2
hypotenuse is the side opposite to the right angle .so here,
H = x .you can take base as 11 and perpendicular as 8
h^2 = p^2 + b^2
x^2 = 8^2 + 11^2
x^2 = 64 + 121
x =
x = 13.60

,so first split them into separate shapes (refer to pic) then calculate each one
I started with the triangle
8×6=48 and 48÷2=24 so the triangles area its 24
next the rectangle
12×8=96
and I did the triangle shape cut out of the square
4×3=12 12÷2=6 so its area is 6
and the squares area is 8×8=64
but u need to subtract 6 from 64 because that area is missing
then you get 64-6=58
then add all the areas
58+24+96 to get your answer of 178m
