Hello,

There are 4 congurent equilateral triangles in ABC and each has an area of (8/5)/4=2/5.
To form the parallelogram we need 2 triangles: 2* 4/5=4/5.

Area of Rectangles and Squares.<br> Please show the work, I need help
USPshnik [31]

Here, I think I can help you out:

1. 21 ÷ 3

= 7

Therefore, the length is 7cm².

2. 35 ÷ 7

= 5cm²

- And so on. Simply divide the area by the length of the side given; you can answer up to question six using this strategy.

7. All sides of a square are the same length.

7 x 7

= 49cm²

9. 2 x 3.5

= 7m²

- The formula to find the area of a square/rectangle is length x width. Just multiply the given lengths for the answers :)

The width of a rectangle is the length minus 4 units. The area of the rectangle is 12 units. What is the width in units of the r
Genrish500 [490]

Answer:

width = 2 units

Step-by-step explanation:

If the length of a rectangle is (x) units, then that means that the width of a rectangle is x - 4 units.

the area of a rectangle is length * width

so just substitute the values that we have now.

x (length) * (x-4) width = 12 (area of rectangle)

so that gives us

x^2 - 4x =12

subtract 12 from both sides

x^2 - 4x - 12 =0

now factor this equation

x^2 + 2x - 6x -12 = 0

x(x+2) - 6(x+2) = 0

(x-6)(x+2) = 0

x = 6, or x = -2 REMEMBER THAT VALUE OF x = LENGTH, IT CANNOT BE NEGATIVE AS YOU CANT HAVE NEGATIVE VALUE OF A SIDE

length = 6, and width = 6 -4 = 2
