Using Pythagoras' theorem its height is 8.660254038
Area = 1/2*10*8.660254038 = 43.30127019 or 43 sq ft to the nearest sq ft
All three sides of an equilateral triangle are..."equal" in length.
An isoceles triangle has TWO sides of equal length but an equilateral triangle has THREE sides of equal length
a equilateral triangle has all the sides the same length.
An equilateral triangle is a triangle with all sides the same length.

Cutting the equilateral triangle in half results in two right triangles each with a base of length x/2, and angles of 30, 60, and 90 degrees. Using the lengths of sides of a 30-60-90 triangle it can be found that the height is (x/2)√(3), which is the same as the height of the equilateral triangle.So the height of the equilateral triangle is x√(3) / 2.
All 3 sides of an equilateral triangle are equal in length Only 2 sides of an isosceles triangle are equal in length
All three sides are equal in length.
An equilateral triangle is one whose three sides are the same length.
An equilateral triangle is a triangle with all sides the same length.
There is a problem with your question, namely that such a triangle does not exist. An equilateral triangle with sides of length 10 would have a height of 5 * (root 3), which is approx 8.66 (not 7 as the question states). An equilateral triangle of side length 10 inches would have an area of 25*(root 3), which is approx. 43.3 inches2.
