What is the length of the longer side in this triangle

Answers


Did you notice the little box with corners marked in the angle down at the bottom ?
That angle is a right angle, and this triangle is a right triangle !

This piece of information is a big help.  It breaks the problem wide open.
You know that in order to find the longest side of a right triangle . . .

-- Square the length of one short side.
-- Square the length of the other short side.
-- Add the two squares together.
-- Take the square root of the sum.

One short side=48.           Its square = 2,304.
The other short side=48.  Its square = 2,304.
Add the two squares:        2,304 + 2,304 = 4,608

The square root of the sum = √4,608 = 67.88 (rounded)


Mom buys a rectangular rug with an area of 7 1/6 square meters. The length of the rug is 3 1/3 meters. What is the width of the rug?

Answers

Answer:

  • 2 3/20 m

Step-by-step explanation:

The area is the product of the length and width

  • The area = 7 1/6 m² = 43/6 m²
  • The length = 3 1/3 m = 10/3 m

Width = ?

  • A = lw
  • w = A/l
  • w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m

The width is 2 3/20 m
