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

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.              

  where a and b are the length and widith  and c is the diagonal length. Let plug it in

900+=2500

40

b=40

d will be the best answer

0.4 liters = 400 milliliters (multiply the volume value by 1000 and it give you the answer). hope this ! ^-^
