Question

A rectangle is 30 inches long. The diagonal is 50 inches how wide is the rectangle?

Answer 1

The answer is 1,500. You have to multiply 30 and 50.

Answer 2

Answer:

40

Step-by-step explanation: A rectangle is  a quadralaterial with 4 90 degree angles made up of two diagonals. If we draw one diagonal, it would split the rectangles into two right triangles. Since a rectangle has a right angle, we can use pythagorean theorem to solve the missing side.              

$a^{2} +b^{2} =c^{2}$   where a and b are the length and widith  and c is the diagonal length. Let plug it in

$30^{2} +b^{2} =50^{2}$

900+$b^{2}$=2500

$b^{2} =1600$

$\sqrt{1600 =$40

b=40
