Answer: 9 centimeters

Step-by-step explanation:

Add up all the sides, 6 + 10 + 11 = 27,

Since it’s the perimeter of an equilateral triangle, you do

27 / 3 = 9, which is the answer.

Madison measured her paper. It was 2/3 feet wide and 1/4 foot long. What is the area of her paper
IRISSAK [1]

Answer:

1/6 squared feet or 0.17 squared feet

Step-by-step explanation:

Since it's a paper, we assume it is a rectangle.

Use the formula for area of a rectangle. A= lw

l is the length and w is the width.

The width is 2/3 feet and the length is 1/4 feet.

Substitute w = 2/3 and l=1/4 into the equation for area of a rectangle.

A = lw

A = (1/4)(2/3)   Multiply both numerators, then both denominators

A = 2/12    Simplify. Top and bottom are divisible by 2

A = 1/6

A ≈ 0.17 Rounded to two decimal places

When you multiply two numbers with units, the answer's unit becomes the squared unit.

Therefore the area of her paper is 1/6 squared feet, or 0.17 squared feet.
