Answer the question and make sure it is squared and in meters please i need help

Readme [11.4K]

Answer:

10,000 square meters.

Step-by-step explanation:

First, let's split this shape into a rectangle and a triangle to make it easier.

Rectangle:

A = bh

We know the base is 120m and the height is 30m. So simply plug those into the equation.

A = (120)(30) = 3,600 square meters.

Triangle:

A = 1/2bh

Since we split the shape up, we have to calculate the triangles base and height.

To find the base, take the 120 and subtract the 40, giving us 80.

To find the height, take the 190 and subtract the 30, giving us 160.

Now take those numbers and plug them into the equation.

A = 1/2(80)(160) = 1/2(12,800) = 6,400 square meters.

Total:

Simply add the area of the rectangle to the area of the triangle to find the area of the entire shape.

A = 3,600 + 6,400 = 10,000 square meters.

❗️❗️❗️Find the length of side x in simplest radical form with a rational denominator.❗️❗️❗️

harkovskaia [24]

Answer:

Step-by-step explanation:

In a 30-60-90 triangle, the ratio of the shorter side to the longer side length is $1:\sqrt{3}$ . Therefore:

$x=\sqrt{3} \cdot \sqrt{3}= \\\\\sqrt{3}^2= \\\\3$

Hope this helps!

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers, (k), she can drive with 12

solong [7]

99 km ... 9 liters
x km ... 12 liters

If the relationship is proportional, we have

$\frac{99}{x} = \frac{9}{12}$

from where

$x = \frac{99*12}{9}= \frac{1188}{9}=\bold{132}$

The answer is 132 kilometers.
