Find the area of the following geometric figure
romanna [79]

The area of the triangle is 90 m²

Explanation:

Given that the base of the triangle is 15 m

The altitude of the triangle is 12 m

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

Area=\frac{1}{2}bh

where b is the base and h is the altitude

Thus, we have,

b=15 and h=12

Substituting the values in the above formula, we get,

Area=\frac{1}{2}(15)(12)

Multiplying the terms, we get,

Area=\frac{180}{2}

Dividing, we get,

Area=90 \ m^2

Therefore, the area of the triangle is 90 m²

Determine measurements of data for the following numbers:
Leno4ka [110]

Answer: mean=87, median=87.5 and range=18

Step-by-step explanation:

Mean:

First add all the numbers

78+95+77+92+87+79+94+86+88+94 = 870

Then you divide the answer by counting the numbers

870÷10

=87

Median:

First arrange the numbers in ascending order (from smallest to largest)

77, 78, 79, 86, 87, 88, 92, 94, 94, 95

pick the two middle numbers which is 87 and 88

then you do \frac{87+88}{2}

                = 175÷2

                =  87.5

range = Largest number - smallest number

= 95-77

= 18
