Answer:
13.29 square meters
Step-by-step explanation:
The two shorter sides of a right triangle have lengths of 9.88 meters and 2.69 meters
Two shorter sides are the base and the height of the right angle triangle
Area of the triangle is 1/2 times base times height
Area of the triangle is 13.2886
13.29 square meters
Answer:
22x-3
Step-by-step explanation:
So -3
And 22 times X is 22x
So the equation would be 22x-3
Answer:
question 8 I believe is B. and then question 7 I think is a.
Answer:
The diagonal of the rectangle is approximately 42.5 inches.
Step-by-step explanation:
The area of a rectangle is given by the following formula:
area = width*length
In this case the width = 2*length, therefore we have:
area = 2*length²
722 = 2*length²
2*length² = 722
length² = 361
length = sqrt(361) = 19 inches
width = 2*length = 2*19 = 38 inches
The diagonal forms a right triangle with the sides of the rectangle, where it is the hypotenuse. Therefore we can use Pytagora's theorem:
diagonal = sqrt(length² + width²)
diagonal = sqrt(19² + 38²) = 42.485 inches
The diagonal of the rectangle is approximately 42.5 inches.
