The answer would be 5/8 and 0.625 in decimal form.


1/-4 - 1/2 * 7/-4 (divide then multiply)

1/-4 - 1 * 7 over 2 * -4 (multiply)

1/-4 - 7 over 2 * -4 (simplify 1 * 7 to 7)

1/-4 - 7/-8 (simplify 2 * -4 to -8)

1/-4 - (7/-8) (move the negative sign to the left)

1/-4 + 7/8 (simplify brackets)

5/8 (simplify).

sveticcg [70]

Answer:

<u>100 m</u>

Step-by-step explanation:

<u>Given</u> :

  • Area of square = 625 m²

<u>#1) Finding the side length</u>

  • Area = (side length)²
  • ⇒ side length = √Area
  • ⇒ side length = √625
  • ⇒ side length = 25 m

<u>#2) Calculating perimeter</u>

  • Perimeter = Total length of the sides of the shape
  • Perimeter = 4 x side length [a square has 4 equal sides]
  • ⇒ Perimeter = 4 x 25
  • ⇒ Perimeter = <u>100 m</u>
