1.625 is the decimal that is between 1.5 and 1.7
Answer:
Step-by-step explanation:
Part A
Area of a rectangle = length x width
Garden area = 7 3/4 x 2 2/3
= 31/4 x 8/3
= 62/3
= 20 2/3 square feet
Part B
5/8 of the area = 62/3 * 5/8
= 31*5 / 3*12
= 155 / 36
= 4 11/36
The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.
Answer:
Step-by-step explanation:
area = ½×base×height
21 = ½(x+1)x
42 = (x+1)x
x² + x - 42 = 0
(x+7)(x-6) = 0
x = -7, 6
-7 is an extraneous solution, so x = 6
