The base of a parallelogram is 21 yards. Find the height if the area of the parallelogram is 525 square
11Alexandr11 [23.1K]

Answer:

25 yards

Step-by-step explanation:

A parallelogram is a quadrilateral (a four sided object) with parallel sides

Some of the characteristics of a parallelogram includes :

  1. Opposite sides  and angles are congruent .
  2. Opposite angels are congruent (D = B).
  3. Consecutive angles are supplementary (A + D = 180°).  
  4. The diagonals bisect each other

Area of a parallelogram = base x height

Area = 525

base = 21 yards

height = ?

525 = 21 x height

divide both sides of the equation by 21 to find the value of the height

525 / 21 = height

height = 25 yards

Three times the difference of x and 2 is greater than -21
svetlana [45]
Three times (3 times something) the difference of x and 2 (2-x) is  greater than (>) -21 (-21)
3 times (2-x)>-21
3(2-x)>-21
distrobite using distributiver poerpoty
a(b+c)=ab+ac
3(2-x)=6+(-3x)=6-3x
6-3x>-21
add 3x to both sides
6>-21+3x
add 21 to both sides
27>3x
divide both sides by 3
9>x
x<9
so x= any number below 9 not including 9
