------------------add
2y = 20
y = 20/2
y = 10 <===

x = 30

If △NMO ∼ △XYZ, and the area of △NMO is 147 square feet, find the area of △XYZ
sladkih [1.3K]

The area of △XYZ according to the figure is 363ft²

<h3>Area of triangles</h3>

The formula for calculating the area of a triangle is expressed as:

A = 0.5bh

  • b is the base
  • h is the height

<h3>Calculate area of each triangles</h3>

For the triangle  △NMO

Area of  △NMO = 0.5bh

147 = 0.5b(14/12)

147 = 7b/12

7b = 12 * 147

b = 252

b = 252ft

b = 3024in

Get the base of △XYZ

14/3024 = 22/XZ

XZ = 4,752in

Area of △XYZ = 0.5 (4,752)(22)

Area of △XYZ= 52,272in²

Area of △XYZ = 363ft²

Hence the area of △XYZ is 363ft²

Some critters got into the oatmeal. They ate 3 packages of Mike's, 2 of Chads, and 6 of Matt's. Toni lost half as much as the ot
Reptile [31]

I think the critters ate 5 1/2 packages of Toni’s oatmeal.

If he ate half as much as the others you should total up the others and divide it by 2.

3 + 2 + 6 = 11 11 divided by 2 = 5 1/2

I hope you find this helpful.
