Each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 feet if there are four blades on the winmail what is the total area of the blades

Given is the shape of a triangle with base = 7 feet and height = 4 feet.

We know the formula for area of triangle is given as follows :-

So, the area of a blade is 14 squared feet.

There are four blades on wind mill. Then area of all four blades would be 4 times 14.

Hence, total area of all four blades = 4 x 14 = 56 squared feet.

the answer is 0.071

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
