Answer:the width of plywood = 6.25 feet wide or 6 1/4 feet wide
Step-by-step explanation:
Step 1
Area of a rectangular plywood = length x width
Area of Ist Plywood= 7 x w
Area of 2nd Plywood= 61/2 x w=6.5 xw
But Total Arae of trhe two Plywoods are = 84 3/8 square feet.
Therefore Our equation to solve the problem becomes
Area of Ist Plywood + Area of 2nd Plywood =84 3/8 square feet.
7w + 6.5w = 84 3/8
13.5w= 84 3/8
w = 84 3/8/13.5
675/8 / 13.5
w=6.25
Therefore the width of plywood = 6.25 feet wide or 6 1/4 feet.
Use the formula:
B refers to the base and H refers to the height of the triangle.
As such, multiply both the base and height of the triangle and divide the answer by 2, to find the area of the triangle.

Let n = number of nickels, and p = number of pennies.
The number of coins is 25, so we get this equation.
n + p = 25
The value of the coins is 0.05 per nickel, and 0.01 per penny.
0.05n + 0.01p = 0.73
Now you have a system of equations.
n + p = 25
0.05n + 0.01p = 0.73
Solve the first equation for n:
n = 25 - p
Now substitute into the second equation.
0.05(25 - p) + 0.01p = 0.73
1.25 - 0.05p + 0.01p = 0.73
-0.04p = -0.52
p = 13
There were 13 pennies.
Now we substitute 13 for p in n + p = 25 to find out the number of nickels.
n + 13 = 25
n = 12
There are 13 pennies and 12 nickels.
Check: 13 pennies and 12 nickels does total 25 coins.
13 * 0.01 + 12 * 0.05 = 0.13 + 0.60 = 0.73
The value is $0.73.
Our answer is correct.
