The perimeter of a square is 24 cm. what is the length of the diagonal

Answers

Answer 1

Answer: A square is equal on all 4 sides and in this problem all sides are equal to 6. Therefore you have an isosceles right triangle with two sides of six making the Hypotenuse 6*the square root of two.
( the rule for an isosceles right triangle is the two legs are equal to X and the Hypotenuse is equal to X* the square root of 2

If 10 men can complete a piece of work in 30 days how many men are requiredto complete the same job in 25 days?

Answers

We must assume that all workmen work at the same rate, and keep it up forever.

More men ==> fewer days

so the proportion is: 30/25 = x/10

Cross-multiply the proportion:

300 = 25 x

Divide each side by 25 :

x = 300/25 = 12 men

Step-by-step explanation:

The picture in this question can be a little deceiving. Each rectangular glass pane is 3 by 10 inches. This means that the picture of the 4 panes overlapping, leaves the center square open. The open area has your inner edges. The question asks for the sum of the inner and outer edges.

Every pane is 10 inches long, so the out perimeter of the figure is 40 inches because the figure has four sides. The rectangles overlap, creating 3 by 3 inch square. 3 inches off either side of a pane leaves 4 inches as the length for the edge of the inner square. Therefore, the perimeter of the inner square is 16 inches.

Outer Perimeter + Inner Perimeter = 40 + 16 = 56 inches
