The area of a triangle is 1,4440 cm^2. The base of the triangle is 5 times the height. What is the height of the triangle?

DochEvi [55]

Answer:

h = 24 cm

Step-by-step explanation:

The formula for area of a triangle is

A = (1/2)bh where b is the base and h is the height.

We are told that the base is 5 times the height, this translates to

b = 5h, so we can rewrite our formula to

A = (1/2)(5h)(h) or

A = (1/2)5h²

We are given A = 1,440, so plug that in and solve for h...

1,440 = (1/2)5h²

2,880 = 5h² (multiply both sides by 2 to get rid of the fraction)

576 = h² (divide both sides by 5 to get the h value by itself)

24 = h (take the square root of both sides)

May someone please help me with this :)

1. The perimeter = 3.7 + 3.7 + 2.8 + 2.8
= 13
The area = 3.7 * 2.8 = 10.36

2. Perimeter = 11.2
Area = half base times height
2.6 * 1.5 = 3.9 squared

The art class is planning to paint a mural on the outside wall this figure is a scale drawing of the wall the scale is 2 inches:

solniwko [45]

Answer:

The area of the actual wall is 693 square feet.

Step-by-step explanation:

Step 1 : Finding the length of the wall in feet.

Length of the wall in the scale drawing = 28 inches

Length of the actual wall = $28 \times \frac{3}{2}$ feet

Length of the actual wall = $\frac{84}{2}$ feet

Length of the actual wall = 42 feet

Step 2 : Finding the width of the wall in feet.

Width of the wall in the scale drawing = 11 inches

Width of the actual wall = $11 \times \frac{3}{2}$ feet

Width of the actual wall = $\frac{33}{2}$ feet

Width of the actual wall = 16.5 feet

Step 3 :

Find area of the wall in square feet.

Area of the actual wall = Length x Width

Area of the actual wall = 42 x 16.5

Area of the actual wall = 693 square feet.
