Answer:

Area = 77ft²

Perimeter = 44 9/20 feets

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Base = 19 1/4 feets = 77/4 feets

Height = 8 feets

Area = 1/2 * 77/4 * 8

Area = (77 * 8) / 8

Area = 77 feet²

Perimeter of a triangle :

Sum of the sides

Perimeter = a + b + c

Perimeter = 19 1/4 + 10 + 15 1/5

Perimeter = 44 + (1/4 + 1/5)

Perimeter = 44 9/20

A rhombus has perimeter 120 M and one of its diagonal is 50 M find the area of the Rhombus
Mademuasel [1]

The area of the rhombus is 829.1562m².

<h3>What is the area of the rhombus?</h3>

A rhombus is a four sides quadrilateral with the four sides equal in length

The area of a rhombus =  \frac{1}{4}d ×√(p² - 4d²)

where p is the perimeter and d is the diagonal

1/4(50) x √(120² - 4 x 50²) =829.1562m²

Need help will mark Brainliest
Bond [772]

Answer:

Step-by-step explanation:

Use similarity here. The ratio will look like this:

\frac{height of Jack}{length of Jacks shadow}=\frac{height of beanstalk}{length of stalks shadow}

using the numbers provided:

\frac{15}{10}=\frac{x}{100} and then cross multiply:

10x = 1500 so

x = 150

Therefore, the beanstalk is 1500 feet tall
