You're finding the area, not the perimeter. The perimeter = 2 times the length + 2 times the width 36 = (2 * 3) + (2 * 15) 36 = (2 * 4) + (2 * 14) How many more like that can you find?

Draw a side view of the situation (The cone will look like an isosceles triangle with a rectangle (the cylinder) sitting on its base and touching the sides) let the radius of the cylinder be r and let the height of the cylinder be h Look at the small right-angled triangle at ...

A trapezoid has a lower base which is twice as long as its parallel upper base. The upper base is 21 cm long. One non-parallel side is 20 cm long and the other non-parallel side is 6 cm longer than the shorter non-parallel side. What is the perimeter of the trapezoid?

MATH! PLEASE REPLY ASAP!
Surface area: The points A and B are the mid-points of WX and XY respectively. For triangle VWX, the surface area is half the base(66) multiplied by the slant height VA of 56. For triangle VXY, the surface area is half the base(32) times the slant height of 63. Add and double ...
