The gadget comes with a page of instructions. When page is unfolded, it is 81 square inches. If one page is nine inches wide what is the perimeter?

What is 9 times 9?

w = width = 9, L = length

Area = Lw
81 = 9L
L = 9

Perimeter P = 2w + 2L
w = 9, L = 9
P = 2(9) + 2(9)
P = ?

Thanks,Helper.

the answer is i don't know and i need the answer

To find the perimeter of the unfolded page, we need to calculate the dimensions of the unfolded page. We know that the unfolded page is a square with an area of 81 square inches.

To find the side length of the square, we can take the square root of the area:

√(81) = 9 inches

Since the unfolded page is a square with equal sides, each side measures 9 inches.

Now, to find the perimeter of the square, we multiply the side length by 4:

Perimeter = 9 inches × 4 = 36 inches

Therefore, the perimeter of the unfolded page is 36 inches.
