Answer:

The perimeter of the square is option E. 16√5 mm.

The area of the square is option A. 80 mm².

Step-by-step explanation:

1. Let's calculate the perimeter of this square:

The perimeter of a square is the sum of its side 4 times, thus:

Perimeter = 4√5 + 4√5 + 4√5 + 4√5

Perimeter = 16 √5

Perimeter = 4 * 4√5 = 16√5

The correct answer is option E. 16√5 mm

2. Let's calculate the area of this square:

The area of a square is the length of its side squared, thus:

Area = (4√5)²

Area = 4√5 * 4√5

Area = (4 * 4 * √5 * √5)

Area = 16 * 5 = 80

The correct answer is A. 80 mm²

What is the least common denominator of 7/9 and 1/12

kvv77 [185]

You could find this by going and doing:
9: 9,18,27,36,45,54,63,72...
12:12,24,36,48,60,72...
36 is the first # that pops up so you could do 36 as a common denominator

A triangle has an area of 80 yd^2 and a height of 10 yd. How long is the base of a triangle? Enter in the answer in the box.

sdas [7]

Answer:

Length of the base is 16 yards.

Step-by-step explanation:

We are given that,

Area of the triangle = 80 yd²

Height of the triangle = 10 yards

Since, we know,

Area of a triangle = $\frac{1}{2}\times Base \times Height$

So, we get,

$80=\frac{1}{2}\times Base \times 10$

i.e. $80=Base \times 5$

i.e. $Base=\frac{80}{5}$

i.e. Base = 16 yards

Thus, the length of the base is 16 yards.
