A rectangle has one side 5 inches and a diagonal of 15 inches. How do you find the perimeter of the rectangle?

Answer 1

Isaiah Anthony

Perimeter of rectangle is # 38.28# inches.

Side and diagonal of rectangular is #s_1=5,d=15# inches

#d^2=s_1^2+s_2^2:. 15^2 =5^2+s_2^2# or

#s_2^2=15^2-5^2=200 :.s_2=sqrt(200)~~14.14# inches

Perimeter of rectangle is #P=2(s_1+s_2)=2(5+14.14)#

#:. P=2*19.14~~ 38.28# inches.

The rectangle's perimeter is 38.28 inches [Ans].

To find the perimeter of the rectangle, we can use the Pythagorean theorem. Since we know one side is 5 inches and the diagonal is 15 inches, we can find the length of the other side using the Pythagorean theorem. Then, we can calculate the perimeter by adding up all the sides of the rectangle.
