How do you find the area of a triangle if the length of two sides is unknown?

It depends on what IS known.
If you know one side and the perpendicular distance from that side to the opposite vertex then it is 1/2*side*perp distance.
If you know two angles (and so all three) you can use the sine rule to calculate both the missing sides.

What is the area of an equilateral triangle with sides of 10 inches and 7 inches?
By definition, an equilateral triangle has all three sides of equal length! So it is impossible for it to have sides of length 10 inches and 7 inches!
If the sides of a triangle are doubled then the area becomes?
If the sides of a triangle are doubled then the area becomes quadrupled (four times as large).
What is area of a triangle whose base measures 3 meters and sides are 20 meters each Height unknown?
A triangle with side a: 3, side b: 20, and side c: 20 meters has an area of 29.92 square meters.
How do you estimate the area of a triangle?
To get the area of a triangle you multiply length by width and divide by two.
A right triangle has a hypotenuse of length 10 and a leg of length 7 What is the area?
A right triangle has a hypotenuse of length 10 and a leg of length 7 has an area of: 24.99 units2
What is the area of a 90 degree triangle?
It depends on the length of the other two sides !
What is the area of an equilateral triangle with sides of 10 inches and 7 inches?
By definition, an equilateral triangle has all three sides of equal length! So it is impossible for it to have sides of length 10 inches and 7 inches!
How do l work out the area of a the perimeter of a triangle?
add up the length of all the sides
How do you work out the area of a scalene triangle?
The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area.
Area of different shapes of equilateral triangle?
There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
What is the area of a triangle that is 12 in and 16 in?
What is 12 in ? And what is 16 in ? ? Are they the lengths of two sides of the triangle ? Are they the length of one side and the height of the triangle ? The area of any triangle is 1/2 of the product of (length of its base) x (its height).
How do you find the area of a triangle while knowing the length of three sides?
Area of Triangle when the length of the three sides is known: square-root [P * (P-2a) * (P-2b) * (P-2c)] / 4 where P is total perimeter and a, b and c are the lengths of the three sides.
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
What is the area of a right triangle that's sides each mesure 3 ft?
If all its sides are the same length it can't be a right triangle on a flat surface. Try it on a sphere...
How do you find the area of a 45- 45 -90 degree triangle?
Depends on the length of the sides ! The simple formula to calculate the area of a triangle is half the base times the height.
How do you find the area of an isosceles triangle with a base of length 7 cm and congruent sides of length 6 cm?
7X6/2
What happens to the area of a triangle if the length and base double?
By length u mean???? diagonal or height.... it doesnt have length If you meant all the lengths of the sides- the area would be 4A (the area (A) times by four).
