Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2L +2W
L is the length
W is the width
If the length of a rectangle is 2 cm less than 7 times the width, then;
L = 7W-2 .... 2
Substitute eqn into the formula for finding the perimeter
P = 2(7W-2)+2W
P = 14W-4+2W
P = 16W-4
If P =60cm
60 = 16W-4
16W = 60+4
16W = 64
W = 64/16
W = 4cm
Hence the width of the rectangle is 4cm
Since l = 7w-
l = 7(4)-2
L = 28-2
L = 26cm
You can proceed and draw a rectangle with the dimension of 4cm by 26cm

Step-by-step explanation:
To determine the number of platelets present in the human body, we need a relation that would relate this value to the given value above which is the number of white blood cells. Fortunately, we are given a ratio of 30. So, we use this value as follows:
number of platelets/number of white blood cells = 30
number of platelets / <span>8×10^3 white blood cells = 30
number of platelets = 240000</span>
