Answer:
87 cm²
Step-by-step explanation:
there is 1 triangle and 1 rectangle in the diagram. so you have to find the area of the both polygons and sum up to find the total area of polygon
area of triangle formula:

1) area of triangle AED
base = 12 cm
height = 4.5 cm
area:

area of rectangle formula:

2) area of rectangle ABCD
length = 12cm
height = 5 cm
area:

3) area of whole polygon
= area of triangle AED + area of rectangle ABCD
= 27 cm² + 60 cm²
= 87 cm²
Calculate the area of the base which is 8.5 * 4 = 34. Next Multiply that by the height of 14 to get 14 * 34 = 476
The volume of the prism is 476 cm³.
Try this option:
note, that the difference between 8 and 10 is 2, between 9 and 12 is 3, between 11 and 16 is 5. It is possible when f(x) is linear function, 2x-6, therefore f(14)=2*14-6=22
Answer: 22.
Answer: 5.9 cm for both triangles.
Step-by-step explanation:
Hi, since the situation forms 2 right triangles we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of a triangle (the longest side of the triangle) and a and b are the other sides.
Replacing with the values given:
c^2 = 3^2 + 5^2
c^2 = 9+25
c^2 = 34
c = √34
c = 5.9 cm
Since both triangles are identical ( same side lengths) the hypotenuse is the same for both, 5.9 cm.
