Answer:
1636 cm^2
Step-by-step explanation:
cut in itwo two shapes a rectangle and isosceles trapizoid
Area - 1/2 hight(base x length)
1/2 x 14(6x17) = 714 cm^2
Area of rectangle- 2(wl x hl x hw) = 922 cm^2
l = 17
w = 13
h = 8
add the areas - 922 + 714 = 1636 cm^2
Answer:

Step-by-step explanation:

Answer:
Area = 20.52 cm^2 and Perimeter = 28.68 cm.
Step-by-step explanation:
Use Pythagoras theorem to find the base of the triangle.
a^2 = 6^2 - 3^2 = 27
a = sqrt27
b^2 = 9^2 - 3^2 = 72
b = sqrt72
Base = sqrt27 + sqrt72
= 13.68
So Area = 0.5 * 13.68 * 3
= 20.52 cm^2 (answer)
Perimeter = 9 + 6 + 13.68
= 28.68 ( answer).
Answer:
A=153
Step-by-step explanation:
Small Base - a=10
Small Base - b=10+7+7=24
Height - h=9
