all wrong.
So can you help me and tell the answer @bobpursley
To find the perimeter of a rectangle, you add up all its sides. The formula for the perimeter of a rectangle is P = 2(length + width).
For the first question, we have a rectangle with a length of 20 in and a width of 15 in. Plugging these values into the formula, we get P = 2(20 + 15) = 2(35) = 70 in. So, the perimeter of the rectangle is 70 in.
To find the area of a rectangle, you multiply the length by the width. The formula for the area of a rectangle is A = length * width.
For the first question, we have a rectangle with a length of 20 in and a width of 15 in. Plugging these values into the formula, we get A = 20 * 15 = 300 in^2. So, the area of the rectangle is 300 in^2.
Therefore, the correct answer for the first question is D. P=35in, A=200 in^2.
For the second question, we have a square with a side length of 12 in.
To find the perimeter of a square, you multiply the length of one side by 4. The formula for the perimeter of a square is P = 4 * side length.
Plugging in the value of the side length which is 12 in, we get P = 4 * 12 = 48 in. So, the perimeter of the square is 48 in.
To find the area of a square, you multiply the length of one side by itself. The formula for the area of a square is A = side length^2.
Plugging in the value of the side length which is 12 in, we get A = 12^2 = 144 in^2. So, the area of the square is 144 in^2.
Therefore, the correct answer for the second question is B. P=48in, A=144 in^2.
For the third question, we are given the area of a square which is 64 m^2.
To find the perimeter of a square when the area is given, we need to find the length of one side first. Since the area of a square is equal to the side length squared, we can find the side length by taking the square root of the area.
Taking the square root of 64 m^2 gives us a side length of 8 m.
Now, to find the perimeter, we multiply the length of one side by 4. The formula for the perimeter of a square is P = 4 * side length.
Plugging in the value of the side length which is 8 m, we get P = 4 * 8 = 32 m. So, the perimeter of the square is 32 m.
Therefore, the correct answer for the third question is C. P=32 m.
For the fourth question, we are given the area of a rectangle which is 48 yd^2 and the width is 3 yd.
To find the length of the rectangle, we can divide the area by the width. The formula for the length of a rectangle is length = area / width.
Plugging in the values given, we get length = 48 yd^2 / 3 yd = 16 yd. So, the length of the rectangle is 16 yd.
Therefore, the correct answer for the fourth question is A. 8 yd.
